Former Rep. Alan Grayson (D-Fla.) thinks Rick Santorum should keep his mouth shut about Internet pornography.

"Rick, if you're against pornography, don't watch it," Grayson said in a campaign email Tuesday afternoon.

Grayson is referring to Santorum's stated belief that a strict reading of current pornography laws would effectively ban hard-core porn on the Internet. Santorum defended that position Sunday on CNN's "State of the Union." The GOP hopeful said he doesn't think Obama is prosecuting pornographers in the same way former President George W. Bush did, and is "putting children at risk as a result of that."

Grayson cited Santorum's Sunday talk show appearance as the reason for the email, where he offered the former Pennsylvania Senator some advice on what topics he should avoid -- including abortion, healthcare, contraception and gay marriage.

"What I'm basically trying to say to Rick Santorum, and everyone like Rick Santorum, is this: mind your own business," the email said.

Santorum walked back his statements about pornography Monday during a radio interview with the Illinois radio show Roe and Roeper.

“I wasn’t talking about the porn industry. We get questions into our website and we post responses. Someone brought it to me three weeks later as a posted response," Santorum said. "To suggest that I’m running on this issue is bizarre. All I said on that issue is that I would enforce the law.”

Grayson is not shy about his opinions. The former Florida Congressman made headlines in 2009 during the healthcare debate when he famously articulated his views about Republicans the floor of the House.

"The Republican health care plan: don't get sick," he said. "The Republicans have a back up plan in case you do get sick ... This is what the Republicans want you to do. If you get sick America, the Republican health care plan is this: Die quickly!"

Grayson is currently running to regain his old House seat in Florida's 8th district. He lost the seat to Daniel Webster (R-Fla.) in 2010.
