The comments are the first from Bill Clinton's office to offer support to the presumptive Democratic nominee since the party's prolonged primary race ended two weeks ago.
Watch: Where is Bill Clinton?
"President Clinton is obviously committed to doing whatever he can and is asked to do to ensure Senator Obama is the next president of the United States," Clinton spokesman Matt McKenna said.
The former president was sharply critical of Obama on the campaign trail earlier this year, and has yet to publicly endorse the Illinois senator, even though his wife officially pulled out of the race June 7.
The comments come three days before both Obama and Hillary Clinton are set to appear together in Unity, New Hampshire, to show their support of a unified Democratic Party. The former president is not slated to attend that event.
Watch: Should Bill stump for Obama?
UPDATE: Responding to the statement, the Republican National Committee notes the former president has been highly critical of Obama, specifically in an interview with PBS' Charlie Rose shortly before the Iowa caucuses when he suggested voting for Obama is a "roll of the dice."
"I mean when is the last time we elected a president based on one year of service in the Senate before he started running?" Clinton said then. "He would have been a senator longer by the time he’s inaugurated, but essentially once you start running for president full-time you don’t have time to do much else.”
