Biden was re-elected to the Senate six times. He became a prominent defender of Israel as a senator, and said that if there was no country like Israel the U.S. would have to make one. Later in his time in the Senate, Biden served as chair of the Senate Foreign Relations Committee and the Senate Judiciary Committee. The Foreign Relations committee deals with American issues in other countries. When Biden was chair, the committee dealt with the 1991 Gulf War, the 2003 War in Iraq, and several treaties. The Judiciary Committee dealt with the choice of Clarence Thomas, Robert Bork, and others for the Supreme Court (SCOTUS). Biden thought that Thomas and Bork should not be on the Court. Though U.S. senators work in Washington, DC, Biden took the train home to Delaware every night.
