The top Republicans and Democrats on the Senate Judiciary Committee have launched an investigation into former Attorney General Loretta Lynch to find out if she interfered with the FBI’s probe into Hillary’s email server.

Chairman Chuck Grassley (R-IA), Ranking Member Dianne Feinstein (D-CA), Lindsey Graham (R-SC), and Sheldon Whitehouse (D-RI) sent Lynch a letter asking for answers after news outlets reported that she told people within the campaign that the FBI’s investigation would not dig too deep.

Politico reported:

The senators are seeking answers about a Russian intelligence memo — which was obtained by the FBI — that suggested Lynch had assured a member of the Clinton campaign, Amanda Renteria, that the investigation into Clinton’s emails would not go too far.

The existence of the Russian intelligence memo was first disclosed in April by The New York Times, which said it played a role in Comey’s decision last year to bypass the normal chain of command and make a public announcement that the FBI was not recommending criminal charges against Clinton. He reportedly was worried that the Justice Department’s credibility could be called into question if the announcement came from Lynch, and Russia later leaked the document.

New details about the intelligence memo came to light in a Washington Post story last month that said U.S. intelligence officials believe it might be unreliable or even a fake.

The senators ask Lynch in the letter if “anyone from the FBI ever discuss or otherwise mention to you emails, memos, or reports” mentioned in the reports from The New York Times and The Washington Post.

Former FBI Director James Comey’s testimony to the Senate also raised red flags when he mentioned that Lynch told him to call the probe a “matter” instead of an investigation. From The Hill:

He told the committee that he was concerned over the former attorney general telling the FBI to refer to the Clinton investigation as a “matter,” not an investigation, which resembled the Clinton campaign line.

He also told the Judiciary Committee last month that he had been worried the Justice Department couldn’t “credibly” decline to prosecute Clinton without “grievous damage to the American people’s confidence in the justice system.”
