ROUGH CUT (NO REPORTER NARRATION) President Donald Trump's former personal lawyer Michael Cohen told the U.S. Congress on Wednesday that when he read reports about a June 2016 Trump Tower meeting between Donald Trump Jr. and Russian government members, he remembered a previous meeting between himself and Donald Trump and his son that had raised his suspicions about allegations of collusion.

Cohen described an incident in which Trump's son, Donald Jr., walked behind his father's desk and told him in a low voice: "The meeting is all set." Cohen said Trump replied: "OK good ... let me know." In hindsight, Cohen said he believed the son was referring to the June 2016 meeting at Trump Tower between a Russian lawyer promising "dirt" on Clinton and members of Trump's campaign.

The sweeping claims against Trump, from a man who once said he would take a bullet for his boss, come as Special Counsel Robert Mueller appears to be close to completing his investigation into possible collusion between Trump's 2016 campaign team and Russian efforts to sway the vote.

Trump has denied having advance knowledge of the meeting, which has come under intense scrutiny in the Mueller probe.
