The National Enquirer's former publisher is expected to return to the stand in Donald Trump's historic hush money trial as testimony continues in the first-ever criminal trial against a former U.S. president. David Pecker was the first and only witness Monday following opening statements. Prosecutors say Pecker worked with Trump and Trump’s then-lawyer, Michael Cohen, on a “catch-and-kill” strategy to buy up and then spike negative stories during the 2016 campaign. Testimony resumes Tuesday. It's the first of Trump's four indictments to go to trial and the first criminal trial against a former U.S. president. He has pleaded not guilty to 34 felony counts.
