Prosecutors will try to rescue Michael Cohen's credibility as a witness when he resumes testimony in Donald Trump's criminal hush money trial on Monday. Cohen directly implicated Trump in the alleged hush money scheme last week, but defense lawyers say he tripped up on cross-examination. Cohen appeared to contradict a previous sworn statement about a call with Trump regarding Stormy Daniels. A big question is whether Trump will break norms and testify, which could distract from Cohen's issues but open him to risk.
