WASHINGTON (AP) — Vice President Joe Biden's son, former Delaware Attorney General Beau Biden, is undergoing treatment at Walter Reed National Military Medical Center.
The vice president's office is not providing any other information about why the 46-year-old has been hospitalized or other details.
Beau Biden suffered a mild stroke in 2010 and underwent surgery at a Texas cancer center in 2013 to remove what was described as a small lesion.
He announced last year that he would not seek a third term as attorney general and instead planned to run for governor in 2016. In January, he joined Wilmington law firm Grant & Eisenhofer, which announced three weeks ago that Biden would be expanding his work there on behalf of whistleblowers.
