David Pecker finally stepped down from the witness stand after more than 10 hours of testimony across four days, where the former American Media Inc. chief described in detail how he helped Donald Trump suppress negative stories and pummel Trump’s rivals in the National Enquirer during the 2016 campaign. The back-and-forth over Pecker’s story set the stage for the further brawls ahead when witnesses such as adult film star Stormy Daniels and Michael Cohen, Trump’s former lawyer and fixer, take the stand.
