Ex-fixer Michael Cohen poised to be key witness in Trump case

Donald Trump's former lawyer Michael Cohen.

A former lawyer for Donald Trump who once said he would do anything to protect the former US president is now poised to serve as a key witness in the criminal trial of his longtime boss.

Michael Cohen, who became a top executive at Trump's real estate company and then his personal lawyer, testified twice before the Manhattan grand jury that voted on Thursday to indict Trump following an investigation into a hush payment to porn star Stormy Daniels before the 2016 US presidential election.
