Vice President Joe Biden is expected to officially announce a bid for the White House, according to Ed Henry, chief White House correspondent for Fox News.

Henry tweeted on Monday that three sources close to Biden say that he has told a number of supporters that he plans to enter the race, but may not officially launch his campaign until this weekend. The announcement may come at the Jefferson Jackson dinner in Iowa, according to Henry.

If Biden does enter the race, he'll be in strong position alongside leading candidates Hillary Clinton and Bernie Sanders.

Biden served in the U.S. Senate, representing Delaware, from 1973 until he took office as vice president in 2009. He previously ran for president in 1988, and again in the 2008 election, when he lost the nomination to President Obama.
