Three members of Maine’s congressional delegation are concerned about the forced resignation of Attorney General Jeff Sessions less than 24 hours after the midterm elections.

Rep. Chellie Pingree said she and fellow Democrats who are taking over control of the House “will be watching to ensure that this isn’t an attempt by President Trump to interfere with the Mueller investigation.”

The Senate Judiciary Committee reported out a bipartisan bill, which I support, that would protect the special counsel’s probe. I urge Leader McConnell to bring this bill to the floor so we can ensure Director Mueller can continue to follow the facts wherever they lead.

Republican Sen. Susan Collins and independent Sen. Angus King agreed that the administration mustn’t impede special counsel Robert Mueller’s investigation into potential coordination between the president’s Republican campaign and Russia.

It is imperative that the Administration not impede the Mueller investigation. I’m concerned Rod Rosenstein will no longer be overseeing the probe. Special Counsel Mueller must be allowed to complete his work without interference—regardless of who is AG.

Trump had criticized Sessions for recusing himself from Mueller’s investigation.

Trump announced in a tweet that he was naming Sessions’ chief of staff Matthew Whitaker as acting attorney general. Whitaker has criticized Mueller’s investigation.
