Ron Paul's Group Swats at Marco Rubio's Immigration Reform Bill

With three of the leading Republican presidential possibilities sitting in the U.S. Senate, theres high drama in the GOP ranks as Sen. Marco Rubio of Florida tries to pass his immigration reform bill -- and how possible fellow 2016 hopefuls Sen. Ted Cruz of Texas and Sen. Rand Paul of Kentucky react to the final bill.

A group affiliated with Pauls father came out swinging against the bill on Sunday. The Campaign for Liberty, associated with former Congressman Ron Paul of Texas, bashed the immigration reform bill -- but not on immigration.

The Senate is set to take up the so-called immigration reform bill tomorrow! the Campaign for Liberty wrote in a message to supporters sent out late Sunday. "And buried deep within the bill are plans to develop a National ID Database of every American citizen, linked with birth dates, Social Security numbers, biometric information -- like photos and retinal scans -- laying the groundwork for full-scale tracking of every aspect of our lives.
