John Kelly recently called Trump a fascist. He’s not the only former staffer to turn against the president.

Elizabeth Neumann, a former Trump-appointed senior official at the Department of Homeland Security, told Politico in a story published Wednesday that she agrees with Kelly’s evaluation that Trump is not fit for office.

She added that the former president has “authoritarian tendencies” and “does not operate by the rule of law.”

Neumann — who in April 2020 resigned from her role as an assistant secretary at the DHS —had also previously railed against Trump.

The former DHS official told NPR in late 2020 that Trump was “throwing fuel on the fire” of domestic terrorism, and earlier said that Republicans’ portrayal of peaceful protests as “lawless” was a distraction from the real threat of right-wing extremism. 

In 2018, Trump appointed four-star general Mark Milley, the former chief of staff of the Army, as the Chairman of the Joint Chiefs of Staff in his administration — a role Milley served from 2019 to 2023. 

When Milley retired from the position in 2023, after serving two years under Trump and two under Joe Biden, he delivered remarks that appeared to be a thinly-veiled jab at Trump. 

“We don’t take an oath to a king or a queen or to a tyrant or a dictator. And we don’t take an oath to a wannabe dictator,” Milley said in his retirement speech, according to the Associated Press. 

And in a new book from Washington Post associate editor Bob Woodward, Milley calls Trump “fascist to the core” and “the most dangerous person to this country,” The Washington Post reported earlier this month. 

Barr was regarded as one of Trump’s closest allies and canniest officials during his stint as attorney general in 2019 and 2020.

He played a key role in fending off legal scandals that embroiled Trump, notably the 2019 release of the special counsel Robert Mueller’s report on Russian interference in the 2016 election.

In 2022, Barr changed course and published a memoir in which he was highly critical of his former boss and said he’d opposed Trump’s bid to cling to power after his defeat in 2020.

He also criticized Trump’s decision to take government records with him to Mar-a-Lago after leaving office, and in a scathing New York Post op-ed article he called on the Republican Party to move on from Trump after the midterms.

“Among the current crop of potential nominees, Trump is the person least able to unite the party and the one most likely to lose the general election,” Barr wrote.

But Barr has since reversed course again, telling CNN’s Kaitlan Collins in April this year that he would be voting for Trump in the 2024 election.  

Christie, the former governor of New Jersey, was one of the first prominent Republicans to endorse Trump when he launched his insurgent bid for the presidency in 2015.

But Christie was fired as the head of Trump’s transition team after his 2016 victory, reportedly at the urging of Trump’s son-in-law Jared Kushner, whose father Christie had prosecuted.

Christie has become a frequent critic of Trump on cable-news shows, and he described Trump as a serial loser in the wake of the 2022 midterms.

More recently, Christie said in an interview with The New York Times earlier this month that he sees “significant” cognitive declines in Trump since 2016 and 2020. And he called out “not only Trump’s willingness but seeming inability to avoid lying about everything” as “toxic to the political environment.” 

Fiona Hill served as Trump’s deputy assistant and the top Russia advisor on the National Security Council in his administration from 2017 to 2019. 

In a 2022 interview with Business Insider, Hill argued that Trump’s election lies have created a “recipe for communal violence” that could foster “civil conflict” in the US. 

And earlier this year, Hill criticized Trump for comparing himself to Alexei Navalny, the late Russian opposition leader and political dissident. 

“What he’s doing in the most brazen and frankly shameful fashion is trying to suggest that the United States is like Putin’s Russia,” Hill told Margaret Brennan on CBS’s “Face the Nation” at the time.
