Sen. Ted Cruz's office has hired a top aide who was recently fired by the conservative Republican Study Committee.

Paul Teller, who was up until recently the executive director of the RSC, will serve as Cruz's deputy chief of staff.

"Paul’s many years of experience working in Congress and his tireless work to advance conservative principles make him a tremendous addition to our team," Cruz (R-Tex.) said in a statement. “I look forward to working with him to keep making Texans’ voices heard in Washington and to promote a positive policy agenda that will restore economic growth, rein in government overreach, and protect Americans’ personal liberties.”

Teller, a veteran of Capitol Hill, was fired last month after the leader of the RSC, Rep. Steve Scalise (R-La.), accused him of working with conservative advocacy groups in a manner that undermined Republican lawmakers.

GOP aides said at the time that Teller had rallied opposition to a budget compromise that passed with strong GOP support in the House.

Tea party groups were quick to decry Teller's ouster.
