Warner, who retired from the Senate after finishing his fifth term last year, will work in the firm’s international practice. Warner will focus on climate change, government contracts, and defense issues.
Warner will not be lobbying for Hogan & Hartson, and the firm says it will strictly adhere to ethics laws.
Warner left the firm as a partner in 1969, when he joined the Department of Defense as undersecretary of the Navy. After serving as secretary of the Navy, Warner pursued elected office. In 1978, he was elected to the Senate, where he spent 30 years on the Senate Armed Services Committee, eventually becoming chairman.
The 82-year-old Warner was once married to actress Elizabeth Taylor. He graduated from the University of Virginia Law School in 1953.
