President Obama has nominated Ronald C. Machen Jr. to be U.S. Attorney in Washington DC.

Machen, 40, was part of the team at WilmerHale that defended defense contractor Mitchell Wade, briber of Randy “Duke” Cunningham.

Thanks to WilmerHale’s efforts, Wade is serving a 30-month sentence. That’s not bad, considering that Cunningham is serving more than eight years and Wade’s former boss and Cunningham briber, Brent Wilkes, is appealing his 12 year sentence.

Machen also represented another corrupt former congressman, Democrat William Jefferson and Christopher Ward, former National Republican Campaign Committee treasurer accused of stealing funds.

The U.S. Attorney is DC’s top law enforcement official, overseeing  the largest federal prosecutors office in the country.

Machen served as an Assistant US Attorney in the Office of the United States Attorney for the District of Columbia, US Department of Justice, from 1997 to 2001.
