I came across a couple of interesting posts regarding federal activity in the Houston, Texas area.
The first was some security detail activity on 168.3500 MHz, N100. Over the years I have caught several security details using this common federal frequency. In at least two cases it was the US Capitol Police providing security for members of Congress. However, I was not able to confirm the P25 NAC on those catches.
Best guess is that this Houston activity was the protective detail for Health and Human Services (HHS) Secretary Sebelius. The original poster also mentioned the code name FLOODGATE was associated with this detail.
Second catch from Houston was on 170.8500 MHz, N864, with some testing in the clear that identified this as "USMS Channel B", with USMS being the US Marshals Service. The P25 NAC of N864 has been speculated as being the US Marshals for a while, but not much has been provided for proof. This catch helps tilt the scales a bit towards confirmation.
