'This Week' Teams With Politifact For Fact-Checking Show Guests

When Jake Tapper took the temporary helm of ABC's "This Week," he asked for suggestions on things the show could do.

One suggestion, live-tweeting the broadcast, has already been implemented.

Now Tapper announces another innovation at the show: fact-checking show guests with Politifact.

The suggestion comes courtesy of NYU Journalism Professor Jay Rosen.

"This week we've invited Pulitzer Prize winning website PolitiFact to fact-check the newsmaker interviews featured on the program," Tapper wrote Thursday. "Obviously I aspire to fact-check newsmakers during the show itself, but in addition to that, starting this Sunday April 12, after the show, you can read Politifact's fact checks on Week and at"

Who will they be fact-checking? This Sunday's broadcast features an all-star lineup of Secretary of State Hillary Clinton, Secretary of Defense Robert Gates and former New York Mayor Rudy Giuliani.
