A Texas Republican on Monday said President Obama's gun control campaign is a fraud based on fake messages over Twitter.

Rep. Steve Stockman (R-Texas) accused Obama of trying to make support for his position look stronger than it really is by flooding Twitter with messages from people who don't exist.

"Obama's anti-gun campaign is a fraud," Stockman said. "Obama's supporters are panicking and willing to do anything to create the appearance of popular support, even if it means trying to defraud Congress," he added. "I call upon the president to denounce this phony spam campaign."

Stockman said that in response to Obama's call for people to tweet their congressman in support of gun control legislation, he received just 16 tweets. But he said all of these messages were identical, and that a closer look at them revealed that only six were from real people.
