Sen. Chuck Grassley (R-Iowa).

Senate Judiciary Committee Chairman Chuck Grassley appeared to send a warning to the White House on Wednesday evening: If you fire Jeff Sessions, we won't confirm you a new attorney general anytime soon.

In a message on Twitter, the Republican senator from Iowa said that "everybody in D.C." should be "warned" that the Judiciary Committee schedule was already set for the remainder of 2017, and therefore there was "no way" discussions about a new attorney general could be held.
