Could it be because President Trump and his family are back at MAL so they have to move the TFR over from his residence in NJ? I think I read somewhere that when a former president changes residence, the TFR moves over to the new residence and stays there until it gets renewed, which is usually often?

I may be wrong here but that's something I read a while ago and if I recall correctly, he had TFR at MAL last winter and there was nothing much going on there other than him being the "former" president.
