Attorney General Merrick Garland during a press conference on Thursday appointed veteran prosecutor Robert K. Hur to special counsel in the investigation into classified documents in possession of President Joe Biden that were found at two locations outside the White House.

Hur joined the Department of Justice’s criminal division in 2003 where he worked in counter terrorism, corporate fraud and appellate matters. In 2018, he was nominated and confirmed to serve as U.S. attorney for the District of Maryland where he supervised national security, corruption and “high-profile matters,” according to Garland.
