Edwards to endorse Obama

WASHINGTON (CNN) -- Former Democratic presidential candidate John Edwards will endorse Sen. Barack Obama on Wednesday at a campaign event in Grand Rapids, Michigan, according to Obama's campaign.

Edwards dropped out of the Democratic race on January 30 after poor showings in the early contests.

He told NBC last week that Obama, the Democratic front-runner, is the party's likely nominee. Both Obama and the his rival, Sen. Hillary Clinton, had sought Edwards' blessing.
