The magistrate judge handling Donald Trump’s arraignment on charges related to trying to overturn the 2020 election warned the former president on Thursday against bribing or influencing witnesses.

U.S. Magistrate Judge Moxila Upadhyaya reminded Trump during the arraignment proceedings that bribing or influencing witnesses, or retaliation against them, is a crime.

While Upadhyaya will oversee Trump’s arraignment, she will not oversee the trial. The case has been assigned to U.S. District Judge Tanya Chutkan, an Obama appointee who has previously handed down strong sentences to Jan. 6 defendants.

The warning to Trump is notable given the House committee that investigated the Jan. 6 attack on the Capitol alleged that the former president and his allies had tried to contact and influence a witness in that probe.

Former Rep. Liz Cheney (R-Wyo.) said at a hearing last summer that Trump tried to call an unnamed witness. She separately described a case of a witness describing receiving phone calls reminding them that Trump was paying attention to who said what.

Transcripts released last December detailed how Cassidy Hutchinson, a former White House aide, dealt with efforts by what she referred to as “Trump World” to diminish the impact of her testimony and withhold information from investigators.
