Three Democratic senators are suing to remove Matt Whitaker from his role as acting attorney general, saying the appointment is unconstitutional and aimed at derailing special counsel Robert Mueller’s investigation. In a statement, Rhode Island Senator Sheldon Whitehouse said, “The stakes are too high to allow the president to install an unconfirmed lackey to lead the Department of Justice—a lackey whose stated purpose, apparently, is undermining a major investigation into the president.” Joining the lawsuit are Senators Mazie Hirono of Hawaii and Richard Blumenthal of Connecticut.
