From Guardian Unlimited:

Brian Jones, McCain’s communications director, and his two deputies, Matt David and Danny Diaz, stepped down but plan to stay on through the week. Two others in the communications shop at the campaign headquarters also are leaving, as are two staffers apiece in Iowa and South Carolina.

Jill Hazelbaker, McCain’s current New Hampshire communications director, is expected to take over for Jones and head up a slimmed-down media operation.
