The District of Columbia Court of Appeals quietly granted a rare waiver this spring to allow D. Kyle Sampson to continue practicing law, despite an ongoing criminal investigation into politicized hiring and firing decisions at the U.S. Department of Justice while Sampson was chief of staff to the attorney general.

Sampson, who left the department in March 2007, was a key figure in scandals that spurred numerous congressional, internal and criminal probes and that ultimately led to the resignation of several top officials, including his boss, Attorney General Alberto Gonzales. Sampson, who has a Utah law license, joined Hunton & Williams as a partner in the firm’s Washington office in October 2007 and applied for membership to the D.C. Bar.
