Following up on Kyra's open mic: CNN has apologized to the White House for the gaffe.

"CNN experienced audio difficulties during the president's speech today in New Orleans," a statement said. "We apologize to our viewers and the president for the disruption."

Paul Gough reports: "It wasn't clear whether it was a technical or human malfunction, and CNN, citing corporate policy, said it wouldn't comment on whether anyone would be disciplined. It seemed unlikely that anyone would."
