White House Counsel Donald McGahn threatened to quit last June because he was "fed up" after President Donald Trump insisted he take steps to remove the special counsel investigating Russian interference in the 2016 U.S. election, a person familiar with the matter said.

The New York Times reported Thursday that Trump backed down from his order to fire Special Counsel Robert Mueller after McGahn said he would resign rather than follow the directive, citing four people told of the matter

Trump on Friday denied the report.
