Sen. Rand Paul (R-Ky.) is the latest potential 2012 presidential hopeful to sign on to speak at social conservative leader Ralph Reed's June conference in Washington, D.C.

Reed's Faith and Freedom Coalition touted Paul as a "Tea Party Champion" in announcing his participation on its website Monday.

The first term senator joins three other rumored GOP hopefuls -- Rep. Michele Bachmann (Minn.), former House Speaker Newt Gingrich (Ga.) and former Sen. Rick Santorum (Pa.) -- for the June event.

Former Alaska Gov. Sarah Palin and former Arkansas Gov. Mike Huckabee are among the other potential candidates who have been invited to speak at the gathering. 

Paul has been traveling to the early presidential primary states and has said he will consider a run in 2012 should his father -- Rep. Ron Paul (R-Texas) -- decide against one. 

In an interview with Radio Iowa over the weekend, Paul said his short time in the upper chamber wouldn't hold him back if he decided to make a run for the nomination next year.
