In a New York Times report Thursday, it was revealed President Donald Trump told White House counsel Don McGahn to fire Robert Mueller -- but McGahn said he'd quit.

The order came last June and it marks the first time "Trump is known to have tried to fire the special counsel," The Times said.

It's unclear if Mueller knew about the incident during the time, but recent interviews from former senior White House officials alerted Mueller's team of the incident. The investigation into Trump not only deals with potential collusion with Russia but whether the president obstructed justice when he fired former FBI director James Comey.

CNN legal analysts Jeffrey Toobin said that it can't be proof of obstruction of justice because Trump never fired Mueller.
