There's "no question" President Donald Trump was involved in an obstruction of justice in his dealings with former FBI Director James Comey, former assistant special Watergate prosecutor Nick Ackerman told CNBC on Thursday.
"The Comey testimony today makes that crystal clear," Ackerman said in an interview with "Closing Bell."
Comey testified before a Senate committee on Thursday that he believed Trump ordered him to drop the probe into former national security advisor Michael Flynn when they spoke in February.
He recalled that the president said, "I hope you can see your way clear to

"The president is entitled to do that. You may not like it. The Congress might decide that is grounds for an impeachable offense, but it is not criminal obstruction of justice," said Ray.
