A congressional staffer who has worked with four representatives over the past four years, including GOP Senate hopeful Rep. Mike Collins (R-Georgia), appears closely tied to an anonymous social media account that denigrates female politicians, promotes political violence, calls for an end to democracy and laments the existence of civil rights laws, among other views, a Washington Post analysis of the account found.
Details shared in posts on the account connect it to 25-year-old Jonathon Hatzistefanou, who works as a legislative assistant for Rep. Daniel Webster (R-Florida) and served as a former staff assistant for Collins, the Georgia Republican locked in a bitter fight for a Senate seat with Sen. Jon Ossoff (D).
Hatzistefanou worked for Collins from May 2023 to March 2024 and has worked with Webster since January 2025, according to federal employee tracker Legistorm. Webster’s term expires in January, and he is not running for reelection. Hatzistefanou also worked as a research assistant with the House Transportation Committee for Rep. Troy Nehls (R-Texas) and interned for Rep. Kat Cammack (R-Florida).
In a brief phone call Thursday, Hatzistefanou denied that the X account is his but declined to comment further. Collins’s office and his campaign did not respond to multiple messages seeking comment, including detailed questions about the account’s content, whether Collins’s office knew of the account and why Hatzistefanou left the congressman’s office after only 10 months.
Within an hour of The Post calling Hatzistefanou, several posts containing slurs or other extreme language were removed from the profile. At that time, Hatzistefanou was the only person The Post had contacted about the account.
The account on X, which uses the name 0UrsaMajor0, repeatedly interacted with Capitol Hill reporters on the website. The account also has repeatedly posted biographical information and details that exactly match those of Hatzistefanou’s life, The Post found. These include his birthday, age, place of residence, information about his colleagues and family members, the location of his office and his extracurricular activities in college.
Adam Pakledinaz, Webster’s communications director, wrote in an email on Friday that “the office was unaware of this account and associated posts. The posts from this account do not reflect the views of Congressman Webster. We will be handling this matter internally.” Pakledinaz did not elaborate further.
Though anonymous, the X account has made its way into the feeds of some influential users. It has more than 1,000 followers on X, and several posts have gained online traction. A post criticizing a Republican’s immigration bill, now deleted, gained hundreds of thousands of views and was reposted by conservative influencers Mike Cernovich and Matt Walsh. The account also is followed by other Republicans who work on Capitol Hill, including a staffer for a member of leadership and a spokesman for Collins’s campaign.
With control of Congress hanging in the balance, Republicans have been grappling with extremism in their ranks, notably among young activists who were revealed to be sharing racist content in group chats and in old social media posts. Sen. Ted Cruz (R-Texas) told the Wall Street Journal in October that the party has a “groyper problem,” referring to a far-right, online political movement, and he is among many conservatives who have recently voiced concerns about the prevalence of such views among young Republican staffers.
The House does not have a blanket social media policy, but its code of conduct that applies to staffers says they must “behave at all times in a manner that shall reflect creditably on the House.”
Much scrutiny has been directed toward people close to Collins, who trails Ossoff in the Georgia Senate race. In May, the publication Slate reported that Collins’s then-chief of staff took part in a group chat with White nationalists. That chief of staff told Slate he was solely acting in his personal capacity. The same month, a campaign operative for Collins reportedly made a joke about the alleged rape of the wife to an adviser for a PAC supporting his primary opponent. Collins has publicly said he cut ties with both.
In August, The Post reported that a different former Collins staffer posted Nazi and KKK imagery. That staffer said his posts were a joke. CNN also reported that Collins’s son-in-law shared Nazi imagery online. Collins has said those views don’t reflect his own and that his son-in-law has had no role in his campaign.
Ossoff has invoked that history in recent debates with Collins, including accusing him of hiring “half the Third Reich.” Collins has said he condemns White nationalism and antisemitism. “Any sort of hate speech, antisemitism, hate of any kind, it’s abhorrent,” he said in an Oct. 13 debate. “I’ve fired people when things happen.”
The account has posted misogynistic comments about women in politics, including calling Sen. Lisa Murkowski (R-Alaska) an “old hag” and referring to Sen. Amy Klobuchar (D-Minnesota) as a “bitch.” A post in June argued that Turning Point USA, the political nonprofit founded by the late conservative activist Charlie Kirk, employed too many women. That post was deleted after The Post contacted Hatzistefanou on Thursday. Another post from September 2024 calls a female former diplomat a “fat pig.”
The account also has used derogatory terms to refer to immigrants and perceived political opponents, especially those who are nonwhite. One post from February 2024, when Hatzistefanou worked for Collins, describes Islam as a “desert slave religion.” 0UrsaMajor0 also has posted that democracy should end and be replaced with authoritarianism.
Hatzistefanou appears to have another, inactive, public X account with the username JonathonHatz. The Post located archived posts where this account retweeted Nick Fuentes, the White nationalist whose fans call themselves “groypers,” twice. This account also posted a homophobic slur. Archives of that account list the same birthday and home state as Hatzistefanou’s.
“I’d rather be a white supremacist than a degenerate impoverished minority,” a JonathonHatz post from June 2017 reads.
Hatzistefanou did not respond to a separate inquiry asking whether that account was his.
The 0UrsaMajor0 X account was created in 2021, the same year Hatzistefanou graduated from University of South Florida St. Petersburg and started his career in politics, as deputy campaign manager for a Florida mayoral candidate, according to LinkedIn. The X account’s oldest viewable posts date back to August 2023, while Hatzistefanou was working for Collins, and roughly eight months after he landed on Capitol Hill as an intern for Cammack. A spokesman for Cammack said in a statement that no one in her office was aware of this account and called its contents “repulsive and disgusting.”
The account’s author has posted a steady stream of extreme and vulgar posts about immigrants, women, center-right Republicans and democracy.
The account has repeatedly lamented that America has become more ethnically diverse through immigration and retweeted posts several times that suggest that the country’s White people have been “ethnically cleansed.”
On Martin Luther King Jr. Day this year, the account posted that the “only thing that matters” is pushing back against the multiracial democracy that developed after the civil rights movement, which the post said has had “unfathomable consequences.”
The account described the civil rights movement of the 1960s as a mistake, writing “Democrats sold their country down the river for progressive moral superiority in the 1960s,” and complained that many Republicans were still committed to civil rights.
Other posts discuss “bioleninism,” a fringe theory that argues the political left maintains its power through organizing a “biological underclass,” a phrase that usually refers to ethnic minorities, gay people and disabled people. Some of those posts were made while Hatzistefanou still worked at Collins’s office as a staff assistant.
“Entropic slime. That’s all the left is. Biomass propagation. Lower order goo,” one post from May 2025 reads.
The account posted several times about the need for American democracy — which one April 2024 postdescribed as “so gay lmfao” — to end and to be replaced by a monarchy or a dictatorship to bring about a right-wing government. The poster also frequently discusses Curtis Yarvin, a blogger and thinker popular in some Silicon Valley subcultures who has advocated replacing democracy with a dictatorship.
One post suggests that Congress, where Hatzistefanou worked at the time, should lose all its power.
“The future we hope for is dependent on Congress becoming a museum,” a post from May reads.
The account once quote-tweeted Senate Minority Leader Chuck Schumer (D-New York) and suggested that he should be subject to trials like those that Nazis faced postwar. “Nuremberg tribunals for every elected official and bureaucrat who pushed even the notion of ‘trans kids,’” a post from June 2025 reads.
“I would pay to watch this f—-t be fed his teeth,” the account wrote about a longtime researcher on far-right movements, using an antigay slur. Other posts also directed the slur toward a former Republican senator and former vice president Mike Pence. These posts were deleted after The Post contacted Hatzistefanou.
On many occasions, the 0UrsaMajor0 account posted personal details that mirror those of Hatzistefanou’s life. For example, the person running the 0UrsaMajor0 account posted their age, now 25, multiple times and posted about a birthday on July 12 on two occasions in 2024. According to his home county’s court records, Hatzistefanou’s birthday is July 12, 2001. The account also posted about completing a political science degree in two and a half years, details that match Hatzistefanou’s education on LinkedIn.
Several posts mentioned the poster as previously living in Florida, and once about participating in debate competitions, both details which are listed on Hatzistefanou’s Legistorm and LinkedIn profiles.
In another instance, 0UrsaMajor0 stated that an office where he had interned had a male colleague depart to work for Roblox government affairs. Hatzistefanou interned for a House Republican whose deputy chief of staff became a Roblox lobbyist last year.
The account also posted about running an unsuccessful college presidential campaign as “the lone right winger on campus.” Both posts were deleted after The Post mentioned them in an inquiry to Hatzistefanou.
Hatzistefanou wrote an op-ed in 2020 asking for votes for his student government campaign at the University of South Florida St. Petersburg. In the op-ed, he likened social justice to cancer. The account also posted about its author having a father with a 20-year career in the Coast Guard. Public records show Hatzistefanou’s father served in the Coast Guard. His father declined to comment.
In January, the account promoted the PIPES Act of 2025 — a reauthorization bill about pipeline safety unlikely to draw much attention. Only a handful of members of Congress co-sponsored that bill — including Hatzistefanou’s boss, Webster.
Along with posting extreme views, the account’s author has expressed resentment about how Republicans might receive those views. In response to a story about a Trump administration official estimating that a high percentage of young Republican staffers are potentially followers of Nick Fuentes, the account argued that was just an excuse so Republicans could promote more average-intelligence “foids,” a derogatory term for women, short for “female humanoid.”
“This is also a means to permanently block gen z, particularly young men, from influence in the GOP,” the post from April states, adding that the “most toe sucking GOP senior staff” would rather promote women “instead of any comptent [sic] gen z men.” That post has been deleted since Thursday.
The author has also criticized Fuentes at times, and posted about being of partial Jewish heritage.
The account repeatedly praised Collins, including for Collins’s use of the slur “tranny” to refer to transgender people in December 2023, when Hatzistefanou was working for the Georgia congressman. “Mike Collins single-handedly fighting the woke mob by normalizing the word tranny again,” the account wrote. “We are so back.”
The post Social account linked to former Mike Collins aide posted slurs, calls for violence appeared first on Washington Post.
