Robert J Costello, scheduled to appear before New York grand jury on Monday, likely to question Trump accuser’s credibility

Mug shot? Perp walk? Fingerprinting? Here’s how it could go down if Manhattan District Attorney Alvin Bragg brings charges.

The grand jury is considering a case against the former president over hush money paid to ex-porn actress Stormy Daniels. The case may see criminal charges brought against Mr Trump. Mr Costello has been called by Mr Trump's legal team to discredit previous testimony by Mr Cohen.

In a social media post over the weekend, former President Trump called for his supporters to protest a possible indictment over an alleged-hush money payment made to adult film star Stormy Daniels in the days before the 2016 presidential election.

Attorney Robert Costello, once a legal adviser to Trump attorney Michael Cohen, will appear Monday before the New York grand jury investigating the former President Donald Trump's alleged role in a scheme to pay hush money to adult film star Stormy Daniels.

Mr Trump posted on his own platform, Truth Social, that he expects to be arrested on Tuesday as part of Manhattan District Attorney Alvin Bragg’s grand jury investigation into a $130,000 hush money payment he is accused of making to the porn star in 2016 via his then-lawyer Michael Cohen in exchange for her silence about an affair the couple are alleged to have had a decade earlier.
