WASHINGTON – Former House Speaker Newt Gingrich is running for president in 2012, ending months of speculation.

The Associated Press reported Monday morning that the Georgia Republican will make the announcement Wednesday over Twitter and Facebook.

Gingrich appeared to confirm it in a tweet saying, "Be sure to watch Hannity this Wednesday at 9pm ET/8pm CT. I will be on to talk about my run for President of the United States."

Several other hopefuls for the Republican nomination have announced their exploratory committees, including former Massachusetts governor Mitt Romney, former Minnesota governor Tim Pawlenty and Rep. Ron Paul (R-TX).
