Rick Santorum blasted fellow Republican candidate Ron Paul as "disgusting" following a media interview Tuesday morning, blaming the Texas congressman for a series of robo-calls insinuating that the former Pennsylvania senator was both pro-choice and against the second amendment.

On Monday night Santorum told voters at an Iowa Pizza Ranch that Paul was behind the calls and that everyone in his family except for his special-needs 3-year-old daughter is an NRA member.

"Believe it or not, someone is out making robocalls suggesting that I am anti-Second Amendment," he said. "Please tell your friends and neighbors that whoever that person is -- Ron Paul -- let's just lay the record out. I am a [National Rifle Association] member, as is every other member of my family. Okay, our three-and-a-half-year-old is not an NRA member yet."
