WASHINGTON (AP) - As Newt Gingrich prepared to abandon his presidential bid, President Barack Obama saw it as an opportunity to swipe at Mitt Romney.
Obama's re-election campaign on Wednesday released an 80-second web video of clips from the Republican primaries in which Gingrich criticizes Romney - Obama's likely Republican opponent - on issues from immigration to his tenure as a venture capitalist.
"Newt Gingrich: Frankly, not Mitt Romney's biggest supporter," says the ad's tagline.
Gingrich planned to formally announce Wednesday afternoon that he is suspending his campaign.
The former House speaker won primaries in just two states - South Carolina and Georgia, which he represented in Congress for 20 years.
His campaign also has reported more than $4 million in debt.
