Donald Trump’s public statements about his indictments have boosted him in the polls, but also are giving prosecutors new material that may be used at trial.

Highlights:

As prosecutors and lawyers for Donald Trump spar over the former president’s public statements, Trump the candidate keeps saying things that could hurt Trump the defendant’s chances in court.

Some of Trump’s public statements have already gotten him in legal hot water, with a partial gag order issued in a civil business fraud trial that is underway in New York, and a hearing Monday on a broader possible gag order in Trump’s D.C. criminal case.

Lawyers said such public declarations are deeply damaging to his defense, as he regularly appears to admit, on video, to particular elements of the crimes he is accused of committing.
