After the 2000 elections produced a 50–50 partisan split in the Senate, Vice President Al Gore's tie-breaking vote gave the Democrats the majority from January 3 to 20, 2001, when George W. Bush took office and Vice President Dick Cheney's tie-breaking vote gave the Republicans the majority once again. Later in 2001, he became Senate Minority Leader again after Vermont senator Jim Jeffords became an independent and caucused with the Democrats, allowing them to regain the majority. He was due to become majority leader again in early 2003 after Republican gains in the November 2002 elections.
