Trump trial moves to cross-examination of David Pecker on 4th day of testimony

David Pecker will end his week where he began: on the stand in former President Donald Trump's New York criminal trial.

The former National Enquirer publisher was the first witness called to the stand after opening statements Monday. Over hours of testimony over three days, Pecker described a scheme in which he agreed to spend tens of thousands of dollars to purchase the rights to stories that might embarrass Trump during his 2016 presidential campaign in order to keep them from being made public, a process known as "catch and kill."

On Thursday, Pecker said that arrangement led him to pay $150,000 to the model Karen McDougal, who claimed to have had an affair with Trump in 2006. Trump denies that relationship.
