Michael Brown, Clear Channel respond to David Sirota's KHOW ouster

Update: As we reported yesterday, David Sirota was suddenly disappeared from the KHOW afternoon-drive show he'd shared since June with Michael Brown; see our original coverage below.

Since that post first appeared, we've received responses from Greg Foster, vice president of programming for the Denver branch of Clear Channel, KHOW's owner, as well as Brown -- not that they provide much more insight into the change.
