A famous publisher outlined a secret plan he had with Donald Trump and his personal lawyer Michael Cohen, calling it an “agreement among friends”.

Prosecutors questioned former National Enquirer publisher David Pecker for nearly three hours.

He testified that the three worked to suppress negative stories about the candidate during his 2016 campaign.

“‘This could be a very big story, so I believe that it should be removed from the market’,” Mr Pecker said he would advise the former president about killing certain articles.

Mr Pecker’s testimony could prove critical for prosecutors as they seek to prove that Mr Trump tried to influence the election by quelling a story of an alleged affair.
