Newt Gingrich will announce he is entering the race for the 2012 GOP presidential nomination on Facebook and Twitter Wednesday.

Fox News has learned Gingrich will do his first post-announcement interview with Sean Hannity Wednesday evening. The former house speaker will headline an economic speech in Washington Friday morning before his public campaign announcement at the Georgia GOP convention in Macon Friday evening.

Spokesman Rick Tyler tells Fox News Gingrich will give a commencement speech Saturday at Eureka College in Eureka, Illinois, the alma mater of Ronald Reagan. Tyler also tells Fox News to expect Gingrich to spend the following week campaigning in the first-in-the-nation caucus state of Iowa.

Gingrich will skip the traditional early campaign phase of forming an exploratory committee and will jump straight into the race with the Wednesday announcement.
