WASHINGTON (AP) — Sen. Thad Cochran has returned to Washington after weeks in Mississippi, where he was being treated for urological problems.

In a statement Tuesday, Cochran says he is pleased to be back in Washington, where he will continue to work on spending bills and vote on the budget later this week.

The 79-year-old senator says he appreciates “all the support and kind words I received while at home.”

The statement says the senator will continue to be treated for urological issues and remains under medical supervision, and that could affect his work schedule.

On Monday, Cochran’s office said he was remaining in Mississippi on the advice of his doctors. Cochran has been away from Washington since the week of Sept. 18.

Lowndes County Sheriff’s deputies and the Bureau of Alcohol, Tobacco, Firearms and Explosives have assisted police in the ongoing investigation.
