Sen. Ted Cruz (R-Texas) will headline the South Carolina Republican Party's Silver Elephant Dinner in Columbia in May.
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.
Cruz's trip comes as other possible 2016 presidential contenders line up speaking events. Former Secretary of State Hillary Clinton (D) and former Florida Gov. Jeb Bush (R) both plan to deliver speeches on the same day in Dallas in late April.
