The Obama administration’s second-term staff reshuffling continued on Monday, as Treasury Secretary Jacob J. Lew named Christian A. Weideman as his new chief of staff. Mark A. Patterson, who has served in the role managing the Treasury Department’s day-to-day operations since President Obama took office in 2009, plans to depart at the end of May.
Mr. Weideman is a well-known presence in the department. A lawyer by training, he is currently the department’s deputy general counsel, and he assisted with Mr. Lew’s confirmation process this year. He has also served as an associate counsel to Mr. Obama and has worked at the Williams & Connolly law firm.
Mr. Lew, a budget expert and former White House chief of staff, took over as Treasury secretary after the long-anticipated departure of Timothy F. Geithner, an international finance expert who is now at the Council on Foreign Relations in New York.
