From Politico:

Rick Perry is expected to drop out later this morning at an 11 a.m. press conference and endorse Newt Gingrich, two sources confirmed to POLITICO.

The news was first reported by CNN.

It gives the surging Gingrich a huge boost heading into the final debate tonight, and the South Carolina primary on Saturday, in which he’s already closing in on Mitt Romney.
