The White House said Wednesday that Vice President Biden's son underwent a "successful procedure" in Houston and will soon return home.

Beau Biden, attorney general of Delaware, sought treatment after a troubling episode during a family vacation. The White House has not released information about his diagnosis or prognosis.

"Yesterday, our son Beau underwent a successful procedure," Vice President Biden and his wife, Jill, said in a statement. "He is in great shape and is going to be discharged tomorrow and heading home to Delaware. He will follow up with his local physicians in the coming weeks."

Beau Biden's office, meanwhile, says he has returned to work.

"This afternoon, Attorney General Beau Biden spoke with Chief Deputy Attorney General Ian McConnel and State Prosecutor Kathleen Jennings about several Department of Justice matters, including the office's ongoing efforts to implement initiatives to combat violent crime in the City of Wilmington and New Castle County," the Delaware Department of Justice said.

It added: "The Attorney General will speak with the Chief Deputy Attorney General and State Prosecutor again tomorrow following his return to Wilmington."
