Did Donald Trump Jr. Commit Perjury? House Intelligence Democrat Suggests Other Trump Organization Members Lied to Congress

As special counsel Robert Mueller's Russia investigation progresses, a question growing all the more pertinent is whether President Donald Trump's eldest son, Donald Trump Jr., committed perjury.

A Democrat on the House Intelligence Committee, which grilled him on his Russian contacts for about seven hours in December 2017, reiterated her belief that Trump Jr. lied to the committee. Representative Jackie Speier of California did not name Trump Jr. on Tuesday when MSNBC Live host Katy Tur asked if she was concerned that anyone in addition to Trump's former adviser Roger Stone lied to the committee. Even so, Speier implied she had the first son in mind.

"I am concerned that other people lied to the committee and I wouldn't be surprised if we find out through the Mueller investigation and report that he has identified others," Speier said.

Tur pushed Speier to elaborate, asking, "Who potentially do you think could have lied?"

"Well, I'm not going to go there with you right at the moment, but I think you could probably figure out. People within the Trump Organization who have testified before the committee," Speier said, a description that fit Trump Jr.

Speier also seemed convinced that Trump Jr. committed perjury and slammed him.

"I will also say that it was so shocking to me that you could swear under oath that you were going to tell the truth, the whole truth and nothing but the truth, and then proceed to lie," Speier said. "But that appears to be something that was very commonplace for some of the people in the Trump orbit."

Speier also bashed another Trump family member during her MSNBC appearance, the president's son-in-law and senior White House adviser Jared Kushner. Kushner told Trump that firing then-national security adviser Michael Flynn would help end the Russia probe, ousted White House transition team chairman Chris Christie claims in his new book Let Me Finish: Trump, the Kushners, Bannon, New Jersey, and the Power of In-Your-Face Politics.

The congresswoman said she thinks so many people have been accused or been found guilty in Mueller's probe "because they thought they were going to get away with it."

"I mean by Jared Kushner's own comments, that after Michael Flynn was fired that he thought the whole Russia issue was over," Speier said, referencing the book. "And they made a calculated mistake."

In early December, Speier said of Trump Jr.: "I think there's at least two occasions where he lied to the committee," and that it could be related to documents they were not able to subpoena due to Republicans.

Trump Jr. told the committee he did not tell his father about the June 2016 Trump Tower meeting he attended with Russians who offered damaging information on presidential candidate Hillary Clinton. But Trump's former lawyer Michael Cohen, who was indicted in Mueller's investigation, disputed Trump Jr.'s claim.
