Rep. Alan Nunnelee (R-Miss.) is “making progress” two weeks after he underwent brain surgery to remove a mass from the right side of his brain.

The two-term congressman encountered complications with his speech and movement after his surgery on June 9.

“Undergoing daily therapy, Nunnelee’s speech continues to improve, and although he has difficulty with his left side mobility, there are signs of improvement,” according to a statement on his congressional website. 

Previously, doctors were unsure if the mass removed from his brain was cancerous because test results weren't completed.

“Doctors continue to be pleased with his recovery after surgery, but they have confirmed that his follow-up treatment will require radiation and chemotherapy,” his staff said.

Nunnelee is undergoing rehabilitation at a Houston hospital, the same rehabilitation center where former Rep. Gabrielle Giffords (D-Ariz.) was treated after she was shot in the head during a rampage in 2011.

According to Nunnelee’s staff, the congressman will continue rehabilitation in Houston for a few more weeks before being moved to Johns Hopkins Hospital in Baltimore where he will be in closer proximity to his congressional office.

At Johns Hopkins, he will undergo radiation and chemotherapy treatment, and outpatient rehabilitation.
