Former President Donald Trump declared on Thursday that President Joe Biden “blew it” when he said about Trump: “We gotta lock him up.”

Trump delivered a fiery response to Biden during a rally in Arizona, one of the swing states he is trying to win in the 2024 White House race against Biden’s vice president, Kamala Harris, in less than two weeks.

“He blew it. He said ‘lock him up.’ He said ‘lock him up’ last night. He’s not allowed to say that! He’s such a stupid guy,” Trump said with a chuckle. “Such a stupid fool.”

After mentioning Trump’s push to cut down the Department of Education during an event in New Hampshire on Tuesday, Biden made the comment about locking him up while making reference to the federal 2020 election interference case against the former president.

Trump “thinks he has a right under the Supreme Court ruling on immunity to be able if need be, if it was the case, to actually eliminate, physically eliminate, shoot and kill, someone who he believes to be a threat to him,” Biden said.

“I mean, so, I know this sounds bizarre. It sounds like if I said this five years ago, you’d lock me up. We gotta lock him up,” Biden said, before adding seconds later: “Politically lock him up.”

White House Press Secretary Karine Jean-Pierre insisted to reporters on Wednesday that Biden meant “lock him out politically,” as in defeating Trump in the election.

However, the damage may already be done. Trump’s lawyers filed a motion to dismiss the 2020 election case, which is led by special counsel Jack Smith, citing Biden’s “lock him up” remark.

Trump of course entertained chants of “lock her up” in relation to his 2016 election rival, Hillary Clinton, and “lock him up” in 2020 when competing against Biden.

Yet Biden took up a similar call while Trump is actually facing federal prosecution under the sitting president’s administration.

During an event on Wednesday in the battleground state of Georgia, Trump said Biden going there amounted to meddling in the 2024 presidential contest.

“I’ve been telling you that it’s election interference,” Trump said. “This is all it is. He said ‘we got to lock him up.’ This is illegal.”
