Trump ally Bob Costello challenges Michael Cohen's credibility in hush money probe.

Trump ally Robert Costello testified before a grand jury and attempted to discredit Michael Cohen's earlier testimony in a hush money probe. Costello claimed that Cohen is unreliable and that he made the payment to Stormy Daniels on his own, not at Trump's request. Cohen fired back, saying that many of Costello's statements were untrue. The grand jury appears to be in the final stages of its investigation, and Trump has claimed he expects to be arrested. A small group of Trump supporters protested outside the courthouse, but the turnout was low.
