Sen. Jim DeMint (R-S.C.) is handing the reins of a caucus of upper-chamber conservatives to Sen. Pat Toomey (R-Pa.).

Toomey will become chairman of the nonpartisan Senate Steering Committee in September.

“Sen. Pat Toomey is a proven and trusted conservative, and I’m very glad he’s taking on this new role,” said outgoing Chairman DeMint. “I’ve fought hard over the last few years to help elect new conservatives to the Senate, and it’s very rewarding to see them step into positions of leadership. I’ve enjoyed chairing this group for the past five years, and I look forward to working closely with Pat and the other Steering members to advance conservative principles at this critical time when our country needs them most.”

“I’m honored to lead the historic Steering Committee,” Toomey said. “It is a privilege to be entrusted with this position. Sen. DeMint has been a courageous leader, and I look forward to building on the great work he has done. The Steering Committee will continue to provide conservative solutions, especially to limit government overreach, restore fiscal responsibility, reinvigorate free enterprise and maintain a strong national defense.”

Toomey, the former Club for Growth president who was elected to the Senate in the 2010 GOP midterm rout, is mentioned on many shortlists as a potential vice presidential pick.
