A former U.S. attorney says it "almost defies credibility" that President Trump was not aware of the June 2016 Trump Tower meeting between Donald Trump Jr. and a Russian lawyer.

The Senate Judiciary Committee on Wednesday released more than 1,800 pages of documents from interviews with numerous figures involved in the meeting, including Trump Jr.

The controversial meeting, when it was revealed, fueled allegations of Trump campaign coordination with Russia – as Trump Jr. was apparently promised dirt on Hillary Clinton’s supposed involvement with Russia.

Trump Jr. told the committee that he didn't tell his father about the meeting, although the White House has said the president was involved in drafting an initial statement about the meeting when news of it broke.

Michael Moore, who served as the U.S. Attorney for the Middle District of Georgia, said the documents don't contain much new information about the meeting itself, but it is interesting to see the steps that were taken to hide that the purpose of the meeting was to obtain dirt on Clinton.

"When we hear that he didn't talk to his father about the meeting and didn't subsequently talk to his father, but rather that Hope Hicks was in the middle of that, that almost defies credibility," Moore said.

He argued that it would not make sense for Trump to be involved in drafting a statement about the meeting if he really had no idea about the meeting or what was discussed.

He noted that Hicks, former White House communications director, exercised her Fifth Amendment right when she was called to testify before Congress, so it's unclear what her role was in the drafting of the statement.
