Washington (CNN) – The Obama campaign is out with a new web video featuring some of Newt Gingrich's fiercest attacks on Mitt Romney, the same day Gingrich is expected to show support for Romney's candidacy.
The video features clips of Gingrich questioning Romney's candor as a politician, querying why he has a swiss bank account, and in response to a question by Wolf Blitzer at a CNN debate, describing Romney as the most anti-immigrant candidate remaining in the race.

On Romney's record as CEO of Bain Capitol, Gingrich accuses Romney of "looting a company" and driving other businesses to bankruptcy. And it features Gingrich in a Fox News appearance during the GOP primaries saying, "The Romney machine can drive down turnout it can run over opponents with negative ads. It doesn't seem capable of inspiring positive turnout and the result is I think very very worrisome if you're thinking about the Fall campaign."
It ends with CBS' Norah O'Donnell asking Gingrich if he's "calling Mitt Romney a liar"?" Gingrich responds, "yes."
The video's snarky tagline: "Newt Gingrich: Frankly, not Mitt Romney's biggest supporter."
Gingrich's broadsides echo attacks the Obama campaign has used to try and define Romney – as a flip flopper lacking a core, a former takeover artist who didn't create jobs but gutted companies, and an anti-immigrant politician.
Gingrich would hardly be the first onetime opponent to endorse a rival. Mitt Romney endorsed John McCain in 2008. Sen Hillary Clinton endorsed then-candidate Barack Obama after their bitterly fought contest the same year.
The point of the video is unlikely to change any voters minds. It's more likely intended as an attempt to goad Gingrich into discussing these past statements, reminding those closely watching the race of the past statements, and forcing these topics back into the conversation.
Because the video was released only to political reporters, statements were not immediately available from the Gingrich or Romney campaigns.
