Didn't catch the NAC's (or the one CC) but Trump landed in Newark, New Jersey earlier this afternoon, and a couple unidentified frequencies (at least in our area) popped up.
163.3150 P25 ENC
171.7625 P25 ENC
173.8875 DMR ENC
382.7500 P25 ENC
407.3750 P25 ENC
And these I know probably aren't federal, but coincidentally became active just minutes before AF-1 landed, and ceased to be so once the motorcade cleared the airport:
404.2875 DMR ENC
405.0125 DMR ENC
405.2875 DMR ENC
405.4000 DMR ENC
408.8625 DMR ENC
