Former "Meet the Press" moderator David Gregory is joining CNN as a political analyst.

Gregory, who has been a guest on CNN and Fox News in recent months, officially started in his new role on Monday morningm according to CNN.

"He will primarily appear on 'New Day," CNN's morning show, according to an internal memo.

Gregory spent about 20 years at NBC News in a variety of roles, including White House correspondent, MSNBC anchor, and "Today" show substitute host.

He succeeded Tim Russert as the moderator of "Meet the Press" and led the storied Sunday morning program for six years.

Gregory was blamed for ratings declines and hindered by comparisons to Russert. In his recent book "How's Your Faith?" he hinted at disagreements with a "new boss," NBC News president Deborah Turness, who was pushing "pretty unorthodox" ideas to change the program.

He twisted in the wind for a while before NBC officially appointed Chuck Todd to replace him. In his book, he calls it "the lowest moment of my professional career."

CNN's addition of Gregory may bolster "New Day" in its daily competition with "Morning Joe," "Fox & Friends" and other morning TV shows.
