Robb was in private practice in
Washington, D.C. from 1938 to 1969. Robb was special counsel to the Atomic Energy Commission at an
AEC hearing on the loyalty of
J. Robert Oppenheimer, the director of the
Manhattan Project. Over the course of four weeks, Robb and the AEC panel interrogated Oppenheimer and other witnesses on his past affiliations with Communists, with Robb using harsh prosecutorial tactics. One observer commented that Robb "did not treat Oppenheimer as a witness in his own case, but as a person charged with high treason." The board ultimately voted 2–1 to strip Oppenheimer of his
security clearance. In 1969, Robb represented
Barry Goldwater in
his libel suit against
Ralph Ginzburg and
Fact magazine, which had claimed that Goldwater was mentally unstable. The jury awarded Goldwater $1 in compensatory
damages and $75,000 in punitive damages, which was upheld on appeal.
Federal judicial service Robb was nominated by President
Richard Nixon on April 23, 1969, to a seat on the
United States Court of Appeals for the District of Columbia Circuit vacated by Judge
John A. Danaher. He was confirmed by the
United States Senate on May 5, 1969, and received his commission on May 6, 1969. He assumed
senior status on May 31, 1982, and was succeeded by Judge
Antonin Scalia. He served in this position until his death on December 19, 1985. ==Personal life==
