President Trump Donald John TrumpUS reimposes UN sanctions on Iran amid increasing tensions Jeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Trump supporters chant 'Fill that seat' at North Carolina rally MORE’s lawyers are clashing over how much to cooperate with special counsel Robert Mueller, The New York Times reported Sunday.

A Times reporter overheard Trump’s top lawyer, Ty Cobb, complaining at a Washington steakhouse about his disagreements with White House counsel Donald McGahn over how to respond to Mueller’s requests in the Justice Department's investigation.

Cobb said at the restaurant that he believed one lawyer was a “McGahn spy” and that McGahn was hiding documents from him that he wanted to access. Cobb also blamed a colleague for “earlier leaks” that he said “tried to push” out Trump’s son-in-law and senior adviser, Jared Kushner, according to the Times.

McGahn privately yelled at Cobb for publicly speaking about the investigation after the Times contacted the White House, according to the newspaper. Chief of staff John Kelly John Francis KellyMORE also reportedly rebuked Cobb.

Cobb is allegedly pushing for the Trump administration to be open with Mueller in his investigation into Russian meddling in the presidential election, while McGahn is pushing for a more restrained approach that could let Trump later assert executive privilege.

McGahn hired a lawyer last week as part of Mueller’s investigation and is likely to be questioned about Trump’s decision to fire former FBI Director James Comey and how White House advisers crafted a statement about Donald Trump Jr.’s meeting with a Russian lawyer during the presidential race.
