The White House is reportedly in turmoil amid fears that the FBI could have seized tapes of conversations between and Donald Trump his longtime lawyer Michael Cohen.

Mr Cohen is known to record conversations with his clients, and his aides fear they may be among the files seized by the FBI on Monday.

“We heard he had some proclivity to make tapes,” one of Mr Trump's advisers told the Washington Post.

“Now we are wondering, who did he tape? Did he store those someplace where they were actually seized? . . . Did they find his recordings?”

On Friday it emerged that Mr Cohen was under criminal investigation by the Department of Justice, after the lawyer went to court in an attempt to block investigators from using the material.
