A number of major television news anchors have been holding secret meetings in an attempt to land an interview with Darren Wilson, the police officer who shot and killed Michael Brown in Ferguson, Miss., this summer.

CNN reported that NBC’s Matt Lauer, ABC’s George Stephanopoulos, CBS’s Scott Pelley and CNN’s Anderson Cooper and Don Lemon have all conducted off-the-record meetings with Wilson. The meetings are unusual because Wilson hasn’t been seen in public since Brown was killed in early August.

After “Reliable Sources” anchor Brian Stelter reported on the secret meetings Sunday, his fellow CNN journalists Cooper and Lemon confirmed via Twitter that the meetings had taken place, apparently in response to critical comments from viewers.
