That's what The Washington Times and DCRTV are both reporting. The Washington Times says:
We hear that a formal announcement will be made today and that the duo will be heard in middays, a time that has suffered in the ratings since Howard Stern's departure for Sirius Satellite Radio forced WJFK to juggle its lineup.
While DCRTV is confirming the midday move, adding that the date of arrival is June 26th, taking over the 10am-1pm time-slot in a tape-delayed show. While this goes along with on-air conversations of new CBS Radio markets opening up, there's still no additional word on what Citadel markets might get picked up.
