Newt Gingrich says he will officially suspend his campaign for president tomorrow.

In a video posted on his website, Gingrich thanked supporters and expressed his gratitude to voters and volunteers across the country.

Despite leaving the race, he says he'll continue to work to bring a new president to the White House.

"A re-election of Barack Obama would be a genuine disaster, and all of us have an obligation, I think, to do everything we can to defeat Barack Obama."

Gingrich won just two primaries in South Carolina and Georgia.

His campaign has reported more than $4 million in debt.
