UPDATE @ 3:00 PM: UPDATE: Sen. John Warner speaks about new job at old firm with National Journal's Jeannette Lee:

Warner said he will draw on his expertise on national security and international trade and "put a good deal of time into environmental issues related to global climate change." In 2007, he co-sponsored a bipartisan bill with Sen. Joe Lieberman, D-Conn., that would have reduced greenhouse gas emissions in the U.S.

He said he has started "quietly working" with Hogan & Hartson, however, his official start date isn't until April.

Warner will not be allowed to lobby his former colleagues, and said he intends to "adhere strictly" to the relevant ethics laws and Senate rules. "I do not foresee my activities, which will be unrestricted with respect to the executive branch, will constitute lobbying," he said.

Since leaving Congress, Warner has been working with archivists at the University of Virginia, where he earned his J.D., to organize personal documents spanning his 40 years in government service. The photos and papers will be made publicly accessible "as soon as they are collated," Warner said.

He said the knighthood recently bestowed upon him by Queen Elizabeth II had "no connection" with Hogan's decision to recruit him.

Former Senator John Warner, R-Va., is rejoining his old law firm, Hogan & Hartson as a partner.

"As I return to the practice of law, I am privileged to rejoin Hogan & Hartson, a firm that has long recognized the value and importance of public service by its members," said Warner in a statement. "This firm provided me with a foundation of learning and experience that helped launch me on my public service career."

Warner joined Hogan & Hartson as an associate in 1961 and became a partner in 1964. In February 1969, Warner left the firm and went to the Department of Defense where he served for over five years in the positions of Under Secretary and Secretary of the Navy.

Thereafter he pursued elective public service, winning his Senate seat in 1978, winning four consecutive re-elections, and becoming the second longest serving senator from the state of Virginia.
