Clinton endorses Obama

WASHINGTON (Reuters) - Hillary Clinton ended her presidential bid and endorsed Barack Obama on Saturday, urging her supporters to unite behind his candidacy and help recapture the White House for Democrats in November.

In the first step toward healing the wounds of a sometimes bitter five-month Democratic nominating battle, Clinton told a cheering crowd at her final rally that she would work hard to put Obama in the White House.

She urged her supporters to unite behind the Illinois senator in his general election race against Republican John McCain.

"I will work my heart out to make sure that Senator Obama is our next president," Clinton told a crowd of about 2,000 at the National Building Museum in Washington. "I ask all of you to join me in working as hard for Barack Obama as you have for me."

With her husband, former President Bill Clinton, and her daughter, Chelsea, standing to the side of the stage, Clinton said she and Obama shared the same values and goals.

"I endorse him and I throw my full support behind him," she said. "We will make history together."

Clinton, a New York senator and former first lady, was once the heavy favorite to become the first female U.S. president. She had resisted calls to pull out of the race for months as the split between their supporters grew wider.

Her mention of Obama's name drew "boos" from some in the crowd, but she said it was time to put aside their differences and concentrate on winning in November.

"This has been a tough fight, but the Democratic Party is a family, and now it's time to restore the ties that bind us together and to come together," she said.

Obama did not appear at the rally, giving Clinton the spotlight for the day. Clinton won more than 17 million votes during the Democratic nominating battle, and Obama has tried to build bridges to her camp ahead of the November campaign.

He watched the speech on a computer over the Internet and tried to call Clinton afterward, an Obama aide said, but did not reach her because she was "understandably" tied up talking to supporters.

Obama said in a statement he was "thrilled and honored" to have Clinton's support and praised her campaign for shattering barriers for women and inspiring Democratic voters.

'A BETTER CANDIDATE'

"Our party and our country are stronger because of the work she has done throughout her life, and I'm a better candidate for having had the privilege of competing with her," Obama said.

The Obama campaign put a link on the front page of its Web site allowing his supporters to e-mail her and thank her.
