CNN Headline News will add conservative radio talker Glenn Beck to its weeknight lineup May 8 at 7 p.m. (ET), with a prime-time repeat at 9 p.m. Encores of the show will run at the same times on Saturdays and Sundays.

“This show is the perfect next step in the evolution of the Headline prime lineup, which has continued to build strength since our revamp last year,” said Ken Jautz, executive VP of CNN Worldwide.

The program shuffle to accommodate Mr. Beck’s show at 7 will mark the end of the live telecasts of “Showbiz Tonight,” which now will be seen on tape at 11 p.m.

“Nancy Grace” will continue to run at 8 and 10 p.m. Both Mr. Beck’s and Ms. Grace’s shows will repeat in late-night at midnight and 1 a.m., respectively.

CNN development veteran Conway Cliff has been named executive producer of “Glenn Beck.”
