Former New Jersey Gov. Chris Christie took a major step toward announcing a potential 2024 presidential campaign this week, as allies reportedly set up a super PAC to support his effort.

The PAC, called Tell It Like It Is, is the latest sign that Christie plans to throw his hat in the ring in the Republican presidential primary race, Fox News has confirmed., Christie, 60, has been one of former President Trump's most aggressive critics since the 2020 election.

The former governor has already made selections for a potential presidential campaign staff as well, according to the New York Times. Mike DuHaime and Maria Comella are poised to manage his campaign if he announces, the outlet reported. Duhaime previously worked as a political strategist during Christie's 2016 campaign, and Comella previously worked as chief of staff to disgraced former New York Gov. Andrew Cuomo.

Meanwhile Brian Jones, a longtime staffer for GOP campaigns, will head up the PAC, the Times first reported.

"I’m very concerned that what we’re heading toward is a Trump-Biden rematch," said in a radio interview. "A Trump-Biden rematch is bad for the Republican Party."

"We lost the House in 2018. The Senate and the White House in 2020. We underperformed in 2022 and lost more governorships and another Senate seat. Donald Trump cannot win," he continued.

Christie was once a major backer for Trump, but turned on the former president after the 2020 election and the subsequent effort to overturn its results.

The former two-term Republican governor and 2016 presidential contender has argued that he has got the debate chops to potentially take down Trump, who is six months into his third White House run and remains the clear front-runner in the early GOP nomination national polls.
