Bruce Schneier, a vocal critic of security measures used by the Transportation Security Administration, was asked to testify before Congress about TSA's security screening initiatives but then was "formally uninvited" after the agency complained.
"On Friday, at the request of the TSA, I was removed from the witness list," Schneier wrote on his blog. "The excuse was that I am involved in a lawsuit against the TSA, trying to get them to suspend their full-body scanner program. But it's pretty clear that the TSA is afraid of public testimony on the topic, and especially of being challenged in front of Congress. They want to control the story, and it's easier for them to do that if I'm not sitting next to them pointing out all the holes in their position. Unfortunately, the committee went along with them."
