From CNN:

Newt Gingrich will officially end his bid for the Republican presidential nomination and formally express his support for Mitt Romney next week, two sources close to Gingrich tell CNN.

Not much to say here. It was well overdue but glad to have him along. Newt Gingrich, no matter my dislike for his 2012 campaign, had and will always be my first Conservative hero from 1994 on, when I first really got into politics. Cheers Mr. Speaker.
