Santorum Endorses Romney
Former GOP Presidential candidate Rick Santorum told supporters in an e-mail Monday that he's endorsing his one-time rival Mitt Romney.
Santorum met with Romney last Friday and told supporters he was fully able to determine where the likely GOP nominee stood on a wide swath of issues.
The former Pennsylvania Senator wrote in his e-mail that above all else the two agree that President Obama must be defeated and that will require "all hands on deck."
Santorum dropped out of the race in early April.
