The Treasury Department says Secretary Jacob Lew's surgery to deal with a benign enlarged prostate went as planned.
Treasury spokeswoman Natalie Wyeth Earnest said that the surgery in New York on Wednesday went well and Lew is now resting comfortably.
She said that Lew expects to resume his normal schedule in Washington next week.
During his absence, some of Lew's duties are being handled by new Deputy Treasury Secretary Sarah Bloom Raskin.
Lew has headed the Treasury Department for a year, taking over in 2013 from Timothy Geithner, who served as Treasury secretary during President Barack Obama's first term.
