The U.S. attorney process could be delayed many more months because of what is known as the "blue slip" process in Congress, which dates to the early 1900s. Traditionally, the administration consults with the senators of each state before choosing U.S. attorneys. Sessions said the Justice Department will ask for help from Congress and "a number of [names] are going over now." The Senate Judiciary Committee sends a blue piece of paper to each senator to voice their approval or disapproval of a U.S. attorney nominee from their home state.
