Santorum Will Suspend Campaign Tonight UPDATE: He's Out; Endorses Rubio

What was rumbled about earlier today is now confirmed. According to CNN, Rick Santorum will be ending his campaign for president tonight, becoming the second candidate to drop out today. Santorum garnered one percent of the vote in his second-to-last-place finish ahead of Jim Gilmore.

Another GOP departure: CNN has learned @RickSantorum will exit race tonight. Plans endorsement.

Unlike Rand Paul and Mike Huckabee, who both dropped out this week, Santorum intends to make an endorsement. There are nine candidates remaining in the Republican primary.

UPDATE: Santorum has endorsed Sen. Marco Rubio (R-FL).

Now: Rick Santorum drops out and immediately endorses Marco Rubio ... reflecting some anti-Trump urgency.
