Removal from office actually doesn't disqualify him from running. It would have to be put up for a separate vote.

Running in 2024 Neither a second House impeachment nor even a Senate vote to convict Trump and remove him from office would prevent him from running again, in 2024 or beyond. Rather, after two-thirds of senators present voted to remove Trump, a simple majority of senators present would have to approve an additional vote to bar him from the presidency in the future. The Senate could not skip the conviction-and-removal vote that requires two-thirds of senators and go straight to the simple-majority vote for future disqualification, Ross Garber, an impeachment and political investigations lawyer who teaches at Tulane Law School, told CNN. There is at least some uncertainty about the disqualification issue, since no president has ever been removed from office by the Senate and only judges have been disqualified from future office. The disqualification language in the Constitution is "disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States"; Garber noted that no court or Congress has ever settled the question of whether the presidency counts as an "Office of honor, Trust or Profit under the United States" from which the Senate is able to ban an impeached and convicted person. (Garber said he personally thinks the presidency does count.)

Was on CNN, so take it with a grain of salt since they are wrong often.
