Update, SAT 2:30 PM: Senator Joe Biden, Barack Obama's pick to be his running mate, is on his way to Springfield, Illinois, where the two will appear before a rally.
A crowd of well-wishers waved to Biden and applauded as he left his home near Wilmington, Delaware, for a flight to Illinois just before noon Eastern time.
Democrats, meanwhile, are coalescing around Obama's selection of Biden as his vice-presidential pick.
New York Senator Hillary Rodham Clinton calls Biden "an exceptionally strong, experienced leader and devoted public servant."
Senate Majority Leader Harry Reid says the Obama-Biden ticket will bring the change the country needs, including a filibuster-proof Senate majority.
The Obama-Biden rally is set to take place at the old state Capitol in Springfield where the Illinois senator kicked off his presidential campaign nearly 20 months ago. They will be be joined by Obama's wife, Michelle; Biden's wife, Jill; and the Bidens' three adult children.

Prevously: (CNN) - Sen. Barack Obama said he has decided on his running mate, but he's not saying who it is.
"I won't comment on anything else until I introduce our running mate to the world," he said Thursday. "That's all you're going to get out of me."
Obama is expected to appear at a rally with his running mate in Springfield, Illinois, Saturday. It's unclear just when the campaign will announce the vice presidential choice via text message.
The top contenders for Obama's No. 2 spot, meanwhile, are staying mum on the selection process as the vice presidential guessing game enters its final hours.
Most of this week's buzz has been around Indiana Sen. Evan Bayh, Delaware Sen. Joe Biden and Virginia Gov. Tim Kaine.
Kaine on Thursday dodged all questions, telling CNN's John Roberts he'd have to plead the Fifth on anything related to the selection process.
"You're just going to have to hear from the campaign and they'll make the announcement when they're ready," he said on CNN's "American Morning."
The first-term governor also would neither confirm nor deny reports he was being vetted, but he said he was flattered to be mentioned as a contender.
"My mom in Kansas City loves it when someone will talk about me as VP," he said.
Kaine also said he thinks that if Obama can take Virginia -- which hasn't voted for a Democratic president in 44 years -- then the senator from Illinois would win the White House.
Kaine will be back in the spotlight later Thursday as he campaigns with Obama in Virginia.
Other candidates at the heart of the VP buzz have largely gone underground: Biden has been seen driving around in his truck, but he's avoided any lengthy interviews. Bayh has also been keeping private -- as much as he can, at least, with reporters staked outside his home.
Darkhorse contender Hillary Clinton re-entered the conversation this week following a poll indicating that nearly half of her supporters have yet to embrace Obama.
The Wall Street Journal-NBC News poll out Wednesday night shows that just 52 percent of Clinton supporters say they will vote for Obama. Twenty-one percent favor Republican John McCain, while 27 percent are still undecided or say they will vote for "someone else.''
The poll has a margin of error of plus or minus 3.1 percentage points.
The New York senator was considered one of the top VP contenders shortly after she ended her own White House run, but rumors of lingering tension between the former rivals and word that her name would be placed in nomination at the convention are partially to blame for kicking her out of the top tier.
Independent presidential candidate Ralph Nader said Clinton is the smart choice because she is the only person who would help Obama get more votes.
"And if he's going to say, 'One people, one nation,' he can raise the banner of unity with her as his vice presidential running mate," he said Thursday on "American Morning."
Nader also told Politico.com that Obama wouldn't be "that dumb" to pick Bayh or Biden to be vice president.
Other big names thought to be in the running include retired Gen. Wesley Clark, Connecticut Sen. Chris Dodd, Texas Rep. Chet Edwards, Nebraska Sen. Chuck Hagel, Virginia Gov. Tim Kaine, former Georgia Sen. Sam Nunn, Rhode Island Sen. Jack Reed, New Mexico Gov. Bill Richardson and Kansas Gov. Kathleen Sebelius.
