Beau Biden Undergoing Treatment at Walter Reed Medical Center

Vice president's oldest son is receiving treatment for undisclosed condition.

The White House has not offered any further comment on Beau Biden's condition.

Beau Biden announced in April 2014 that he would not be seeking a third term as Delaware attorney general to instead pursue a run for governor in 2016.

Just three weeks ago, Beau Biden's firm, Grant and Eisenhofer, announced that Biden would be expanding his work with the firm's whistleblower clients.
