Democratic U.S. Senator Joseph Biden of Delaware has announced he is seeking his party's 2008 presidential nomination.
Biden announced his intention to enter the race on American television Wednesday.
Biden is currently the chairman of the Senate Foreign Relations Committee and is a prominent critic of President Bush's Iraq war strategy.
On his campaign web site, the senator highlights his plan for Iraq, which calls for most U.S. troops to withdraw by the end of 2007.
Biden has served in the U.S. Senate for more than 30 years. He lost a previous bid for the Democratic nomination in 1988.
More candidates are expected to join the race to be the Democratic Party's nominee, a field that has been dominated so far by popular senators Hillary Clinton and Barack Obama.
