Donald Trump Jr. refused to tell the House Intelligence Committee what he told his father, President Donald Trump, regarding his infamous meeting with a Russian lawyer at Trump Tower back in June 2016 after being told he'd receive dirt on then-candidate Hillary Clinton.

According to Rep. Adam Schiff (D-Calif.), Trump Jr. cited client privilege as the reason he didn't tell Congress any details about what he told his father after the meeting during Wednesday's eight-hour-long testimony.

But the ranking member of the House Permanent Select Committee on Intelligence pushed back on the president's son's reasoning, saying he can't apply attorney-client privilege and “shield” investigators from information about the Trump Tower meeting because an attorney was present in the room at the time, per The Hill.

“He acknowledged having discussed the June 9 meeting and the emails that went into establishing that meeting after those emails became public,” Schiff said Wednesday following a closed-door meeting with Trump Jr.

It was reported earlier Wednesday that Trump Jr. informed House investigators that instead of communicating directly with his father after news broke on reports of his June 2016 Trump Tower meeting, he spoke to then-White House aide Hope Hicks regarding how the president should respond.
