It's heating up within the New York Court room as Donald Trump's lawyers grill his former fixer. 

Michael Cohen was an attorney for the ex-president from 2006 to 2018 and the prosecution's last witness in the hush money trial. 

He's told the prosecutors he allegedly paid adult star Stormy Daniels on behalf of Trump, to ensure the story would not come out before the 2016 election. 

US correspondent Richard Arnold told Andrew Dickens that it's already a tense cross examination. 

He says Trump's lawyer started by calling out Cohen for posting rude Tiktoks about him.
