Sen. Frank Lautenberg (D-N.J.), who is undergoing treatment for lymphoma of the stomach, will return to work in the Capitol next week, his spokesman said Saturday.

Caley Gray said Lautenberg is expected to return for votes Tuesday.

Lautenberg, 86, was released from Mount Sinai Medical Center in New York on Thursday, where he had stayed for 10 days after being admitted Feb. 15. Lautenberg initially was taken by ambulance to the hospital after falling at his home in Cliffside Park, N.J. Tests revealed that Lautenberg had lymphoma of the stomach, and he swiftly began chemotherapy treatment that will last over the next two months.

The Senator’s last vote was on Feb. 9. On Tuesday, the Senate is scheduled to vote on a cloture motion for the nomination of Barbara Milano Keenan to serve on the 4th Circuit U.S. Court of Appeals.
