White House counsel Don McGahn has extensively cooperated with special counsel Robert Mueller's probe into Russian meddling, providing comprehensive detail on how President Trump has responded to the investigation, according to a report in the New York Times.

The report said that McGahn has met with Mueller's team three times. He spoke about Trump's response to various events such as the firing of former FBI director James Comey and Trump's push to install a loyalist to oversee the probe.

The newspaper noted that it is unusual for an attorney to share such intimate details about a client. McGahn started to cooperate with the probe due to a decision by Trump's first legal team to cooperate with Mueller and hopefully end the probe quickly.

McGahn and his attorney William Burck decided to cooperate as much as possible with the probe to demonstrate that he did nothing wrong, a nod to head off a potential strategy by Trump to take the blame for any possible criminal acts of obstruction, the Times reported.

Trump has repeatedly referred to the Mueller investigation as a political "witch hunt."

McGahn also played a pivotal role in preventing Trump from firing Mueller, which the president considered last year. McGahn told Trump that he would resign if Mueller was fired, which prompted Trump to back off, according to multiple reports.
