    Reacting to the news, Obama praised Edwards on Wednesday for spending a "lifetime fighting to give voice to the voiceless and hope to the struggling, even when it wasn't popular to do".
     
    Clinton also told NBC that it was crucial to remember the "very important" contribution Edwards made "to encourage us to focus on poverty".
     
    Edwards did not indicate whether he endorsed either Obama or Clinton for the nomination, although such a seal of approval could boost either's campaign.

    Meanwhile it is widely expected that Rudy Giuliani, former New York mayor, will drop out of the Republican presidential race on Wednesday evening.
     
    Giuliani finished a distant third in the Florida primary on Tuesday, behind winner John McCain and Mitt Romney.
     
    He had once been considered the Republican frontrunner, however a risky strategy of gambling much of his campaign success on winning Florida backfired after John McCain, the Arizona senator, surged in polls.
     
    Sources within the Republican party said Giuliani would announce he is to endorse McCain after leaving the campaign.
     
    The Republican presidential candidates are due to take part in the latest presidential debate at the Ronald Reagan Presidential Library in Simi Valley, California on Wednesday night.
     
    Previous campaigns

    He ran for the Democratic presidential nomination in 2004 and after losing was picked by John Kerry as his prospective vice president in that year's White House race.
     
    However Kerry lost the election to George Bush.
