I would bet the White House was CERTAINLY bugged at the very least. There was time between the Inauguration and the election.
For those who've never read it, early in the book House Atreides is granted fiefdom over Arrakis, the desert world that is the source of melange, the most precious substance known. The planet had formerly been held by their mortal enemies, the Harkonnens (evil, corrupt, hedonistic, too much into homosexuality).
Prior to the Atreides arriving and taking over the palace, the Harkonnens hide bugs, booby traps, sabotage of critical systems, and suicide agents all OVER the place. One is able to make an almost successful assasination attempt on Paul, the Atreides prince.
At this point, it wouldn't surprise me at all if House Obamanation had a hitman waiting in some neglected recess of the White House...
Trump needs to hire at least three different sniffer companies, trusted former Vets, to come in and completely sweep the place. . and then do it monthly.
