NBC Nightly News anchor Brian Williams was the first of the Big 3 anchors to get on the ground in Haiti, and spent several days reporting on the damage and devastation.

We talked to Williams this week about the experience and the story, still dominating the evening news on a regular basis, in the latest Q&A in our “Back From Haiti” series.

CNN has covered the Haiti story far more than any other cable news network – last week it was four times as much as Fox News or MSNBC. And it continues this week, with CNN anchor Anderson Cooper remaining the most high profile correspondent still reporting on the ground (he’s there all week, and has been since January 13). Mediaite spoke to Cooper today (instead of “Back From Haiti” it’s “Still In Haiti”) while he traveled from “mass graves” to the Hotel Montana, where people are “digging for Americans foreign nationals.”

CNN correspondent Soledad O’Brien returned from Haiti on Friday after several days of reporting about and following the story of a group of orphans from Haiti to Miami. And it wasn’t just on TV – O’Brien gave a full play-by-play on her Twitter feed in real time.

We spoke to O’Brien Friday afternoon for our “Back From Haiti” series, as she returned to New York – and to her family.

Fox News anchor Bill Hemmer returned from Haiti this week, after covering several aspects of this tragic story. His excellent reporting brought the images of Haiti into viewers homes, like many other correspondents on the array of news outlets. Earlier this week we spoke to his colleague Steve Harrigan – Mediaite spoke to Hemmer yesterday afternoon.

Fox News reporter Steve Harrigan has covered the war in Afghanistan and Hurricane Katrina. But of the Haiti devastation, he calls it “a mini-Rwanda.”

Mediaite spoke to Harrigan by phone today, hours after he delivered another heart-wrenching report.
