Jim Manley, chief spokesman for Senate Majority Leader Harry Reid (D-Nev.), said Thursday he is resigning his post  after more than 20 years in the Senate.

Manley told The Hill he had "no idea" what he would do next.

"After more than 20 years in the Senate, including one full six-year cycle with Sen. Reid, it's about time for me to try something new," Manley said. "While I love the Senate very much, and had a great time working for Sens. Mitchell, Kennedy and Reid, I'm itching for a new adventure."

Manley worked as an aide to Sens. George Mitchell (D-Maine) and Edward Kennedy (D-Mass.) before signing on with Reid.

Manley said he had "no idea" when he would actually leave the office. "I have time to work on it," he said.

Reid said his office would miss Manley's insight, candor and sense of humor.

“Jim is one of best communicators I have ever had the fortune of working with," he said in a statement. "He represents the very best of our party and our country, and there are countless young communicators who owe him a tremendous debt of gratitude for paving the way. 

“Our office will sorely miss Jim’s insight, candor and sense of humor, all of which have made it easier for me to do my job.  Jim has earned the respect of Senators and staff members on both sides of the aisle, and I am proud to call him a friend.  I know that whatever challenge he decides to tackle next, he will be the best man for the job.  Landra and I wish him the very best on his future endeavors.”
