A story that aired on the “Today” show last week caught the attention of media watchdog group Media Research Center, whose founder then went on Fox News’s “Hannity” Friday night to share what they’d uncovered: selective editing of a 911 call in the Trayvon Martin case.

After the Fox News segment and calls from media reporters, NBC News says it is investigating the story. “We have launched an internal investigation into the editorial process surrounding this particular story,” a spokesperson told the Washington Post’s Erik Wemple Saturday.

Here’s how the “Today” show story, reported by Ron Allen last Tuesday, included the call:

Zimmerman: This guy looks like he’s up to no good. He looks black.

Here’s how the conversation happened, with the dispatcher’s question:

Zimmerman: This guy looks like he’s up to no good. Or he’s on drugs or something. It’s raining and he’s just walking around, looking about.

Dispatcher: OK, and this guy — is he white, black, or Hispanic?

Zimmerman: He looks black.
