Twelve audio recordings seized from U.S. President Donald Trump's onetime personal attorney, Michael Cohen, were turned over to federal prosecutors on Friday, according to a filing in federal court in Manhattan on Monday.

They include a recording of a conversation between Cohen and Trump two months before the November 2016 election, whose existence was made public last week, in which they discussed buying the rights to a story by a woman who said she had an affair with Trump, according to Rudy Giuliani, one of Trump's lawyers. The other recordings are of conversations in which Cohen mentions the president to someone else, Giuliani said.

In the September 2016 conversation, Trump and Cohen discussed paying the parent company of the National Enquirer tabloid for the rights to the story of former Playboy model Karen McDougal, Giuliani previously said in an interview.
