Reports from the Washington, DC area have the US Park Police doing some sort of radio programming changes in preparation for the upcoming Presidential Inauguration. Postings indicated that USPP officers were being notified to bring radios in for re-programming last week. And recently there were some indications that there were some on-air testing of a "Special Events Channel". No indication of what frequency that channel might be, but some speculation that it may be on the NCR IWN trunked system. More as it becomes available.
You can get a preview of possible active radio frequencies for the Inauguration on the latest issue of the Capitol Hill Monitor newsletter. You can find the latest issue here:
