Donald Trump's lawyers continue to cross-examine his former fixer in court in a potential turning point of the hush money trial. 

Michael Cohen was an attorney for the former-President from 2006 to 2018 and is the prosecution's last witness. 

He's told the prosecutors he 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 Mike Hosking that Cohen previously said he'd do just about anything for Trump. 

He says after serving jail time, Cohen believes Trump should 'rot' for what he did to Cohen and his family.
