Howard Kurtz talked to Jenna Lee on Happening Now this afternoon to discuss this weekend's Media Buzz, which includes a must-see sit-down with former CBS News investigative reporter Sharyl Attkisson. Attkisson detailed on The O'Reilly Factor last night the pushback she received when she began looking deeply into Obama administration scandals like Benghazi and Fast and Furious.

She revealed that she was labeled a “troublemaker” for pursuing the Benghazi story after the network had clearly lost interest in it.

In an extended interview, Attkisson will reveal even more about her time at CBS and the pushback she received from higher-ups and from within the Obama administration.

Howard will also delve into the media's coverage of Kathleen Sebelius' exit and the Stephen Colbert "Late Show" announcement on Media Buzz, Sunday at 11a/5p ET.
