Trump and other former White House officials could be called to testify in billionaire Thomas Barrack's trial

Former President Donald Trump or members of his administration could be called as witnesses in the trial of Thomas Barrack, a billionaire friend of Trump accused of unlawfully lobbying on behalf of the United Arab Emirates, a federal judge said Tuesday.

On Monday and Tuesday, Judge Brian Cogan repeatedly asked potential jurors who had indicated they had strong opinions of Trump if they could be impartial if he were called as a witness.

"It's possible in this case that maybe former President Trump, maybe someone from his administration, might be called as a witness," Cogan told one possible juror Tuesday.
