Gingrich in Virginia to quit, Romney in Virginia to campaign, plus more to watch for Wednesday in politics

Newt Gingrich is scheduled to officially end his campaign Wednesday afternoon in Arlington, Va. — a development that was anticipated for some time and announced last week.

"All of us have an obligation I think to do whatever we can to defeat Barack Obama," Gingrich said in a video released Tuesday that did not mention Mitt Romney. "I want you to know that we're going to continue out there on the road. Callista and I will be talking, campaigning, making speeches, doing everything we can to help defeat Barack Obama."

Romney also will be in Virginia, a key battleground state in the general election. At some point during Romney's swing through Virginia, Gov. Bob McDonnell, a potential running mate, will appear with him.

And then there is this: President Barack Obama participates in an Ambassador Credentialing Ceremony at the White House where he will receive credentials from foreign ambassadors recently posted to Washington, D.C. The event is a traditional ceremony that marks the formal beginning of an ambassador's service.

And this: The John Edwards trial continues, and Cheri Young, wife of former aide Andrew Young, will be back on the witness stand.
