LINCOLN, Neb. (AP) — Nebraska Attorney General Doug Peterson has returned to work after undergoing surgery for early-stage prostate cancer.

A spokeswoman confirmed that Peterson came back to the Capitol on Tuesday after doctors gave him a clean bill of health.

The 55-year-old Peterson underwent surgery at an Omaha hospital earlier this month. He left the hospital after a 24-hour observation period and has been conducting business from home.

Peterson, a Republican, took office in January after former Attorney General Jon Bruning opted not to seek a fourth term.

Bruning underwent successful surgery in 2013 to remove part of his colon and surrounding lymph nodes after he was diagnosed with colon cancer.
