Cruz will be the keynote speaker at the May 3 dinner, Cruz's office confirmed to The Hill.   

Cruz's trip to South Carolina, a coveted presidential primary state, will likely spark speculation that he is toying with the idea of running for president in 2016. 

The junior senator from Texas has only been in Congress a few months, but he's already caught national attention as a conservative firebrand. 

The 2013 Silver Elephant dinner will reportedly focus on former Sen. Jim DeMint (R-S.C.). DeMint stepped down from office in early 2013 to run the conservative Heritage Foundation. DeMint endorsed Cruz during Cruz's primary campaign against Texas Lt. Gov. David Dewhurst.
