WASHINGTON (CNN)– Vice President Joe Biden will be in Iowa Saturday as a special guest at the Iowa Democratic Party's annual Jefferson Jackson Dinner.
Joining Biden will be Gov. Chet Culver, Lt. Gov. Patty Judge, and Reps. Bruce Braley and Leonard Boswell. According to the Iowa Democratic Party, Sen. Tom Harkin is also expected to speak, but may miss the event if he's delayed by the Senate health care vote Saturday.
The annual dinner is one of the biggest Democratic fundraising events of the year, usually kicking off the presidential primary season. In 2007, then-candidate Barack Obama's speech at the dinner has been credited to launching his path to the Democratic nomination. Hillary Clinton, John Edwards, Chris Dodd, Bill Richardson and Biden also spoke in 2007. Speakers in past years include former President Bill Clinton and former Vice President Al Gore.
The event is being held at the Iowa Events Center in Des Moines.
UPDATE: According to the Iowa Democratic Party, Sen. Tom Harkin will not be able to attend the dinner Saturday night, but has filmed a message to be played at the event.
