(CNN) Sen. Barack Obama has picked Delaware Sen.to be his running mate.
Delaware Sen. Joe Biden has been tabbed as Sen. Barack Obama's vice-presidential running mate.
The longtime Democratic senator was long considered a likely choice for vice president, but the buzz surrounding him intensified after he returned earlier this week from a two-day trip to the Republic of Georgia after Russian troops invaded.
Biden, chairman of the Senate Foreign Relations Committee, brings years of experience that could help counter GOP arguments that an Obama administration would be inexperienced on foreign policy.
Biden abandoned his own White House run after a poor showing in Iowa's first-in-the-nation caucuses. He also ran for the 1988 Democratic presidential nomination but dropped out after charges of plagiarism in a stump speech.
The 65-year-old was first elected to the Senate in 1972. Shortly afterwards, his first wife and daughter were killed in a car accident. He considered resigning, but decided to continue with his political career.
Biden is currently serving out his sixth term, making him Delaware's longest-serving senator.
Biden is married and has three children. He received his undergraduate degree from the University of Delaware and got a law degree from Syracuse.
In 1988, Biden suffered an aneurysm and nearly died but has recovered fully.
One of Biden's grandfathers was a Pennsylvania state senator, according to the Almanac of American Politics.
Biden will make his first big speech as the VP candidate on Wednesday, August 27 -- the third night of the Democratic convention.
