NEW YORK — Donald Trump’s defence team attacked the credibility Friday of the prosecution’s first witness in his hush money case, seeking to discredit testimony detailing a scheme between Trump and a tabloid to bury negative stories to protect the Republican’s 2016 presidential campaign.

Returning to the witness stand for a fourth day, former National Enquirer publisher David Pecker was grilled about his memory and past statements as the defence tried to poke holes in potentially crucial testimony for prosecutors in the first criminal trial of a former American president.
