By MICHAEL R. SISAK, JENNIFER PELTZ, MICHELLE L. PRICE and ALANNA DURKIN RICHER (Associated Press) NEW YORK — With prosecutors’ hush money case against Donald Trump barreling toward its end, their star witness will be back in the hot seat Thursday as defense lawyers try to chip away at Michael Cohen’s crucial testimony implicating the former president. The trial, now in its fourth week of testimony, is resuming in Manhattan with potentially explosive defense cross-examination of Cohen, whose credibility could determine the presumptive Republican presidential nominee’s fate in the case. Cohen is prosecutors’ final witness — at least for now — as they try to prove Trump schemed to suppress a damaging story he feared would torpedo his 2016 presidential campaign and then falsified business records to cover it up. With the defense not expected to call many — if any — witnesses, Cohen’s cross-examination is a pivotal moment for Trump’s team, which must convince jurors that his once-loyal attorney and fixer can’t be believed.
