Cruz's comments come as Congress debates passing a set of gun-control measures meant to reduce gun violence and prevent shooting massacres similar to the one at Sandy Hook Elementary School in Newtown, Conn. A number of Democrats in red states have balked at the gun control proposals Obama and Democratic leadership hope to pass. Cruz said that passing the gun proposals will likely result in some Senate Democrats losing their seats in 2014. 

"In fact, in my view, as a result of their onslaught on the Second Amendment right to keep and bear arms, I think there's going to be a very significant consequence in 2014," Cruz added. "I think as a result of this fight that President Obama is picking, I think the stage is set for Republicans to take control of the United States Senate because of this fight right now, because of coming after the right to keep and bear arms of peaceful law-abiding Americans. I think a number of red state Democrats who are up for reelection in 2014 are going to lose their seats and I think they should."

Cruz and a number of other Republican senators have threatened to block Reid's move with a filibuster. That threat has been met with criticism by both Democrats and some Republicans. The Wall Street Journal's editorial page on Wednesday criticized Cruz and the other roughly dozen Republicans for the threat. Cruz brushed off that criticism.

"I think the criticism has been silly," Cruz said before adding that "the Republicans who are saying that they are happy to vote to shutoff debate and move to the bill, they don't even know what the bill contains.

"The bill that these Republicans are going on television saying 'we've got to move to and vote on,' they still don't know the details because the Democrats haven't released the details of the bill that they're moving to proceed to."
