Sen. Richard Blumenthal (D-Conn.) is urging the chairman of the Senate Judiciary Committee to subpoena Donald Trump Jr. to testify publicly before the panel. 

The Democratic senator, a member of the committee, sent a letter to Sen. Chuck Grassley (R-Iowa) on Tuesday asking him to “immediately issue a subpoena for public testimony and documents from Donald Trump, Jr.”

“Recent revelations have shown beyond question that the American people can only feel certain that Mr. Trump, Jr. has been fully forthcoming if he is subject to a subpoena,” Blumenthal wrote.

He added that the Senate Judiciary Committee should “issue a subpoena to compel him to fully account for his actions in front of the American people and to provide this committee with the documents we need to fulfill our important oversight responsibilities.”
