inside the TFR area, no flight of UAS is allowed per the NOTAM (under the PL 112-95 sect 336, you could make an argument that they decided not to regulate 'hobby aircraft' under 400' and within LOS that did not pose a danger to the NAS; however i doubt the FAA would be very receptive to this argument if you're in their TFR). PLus, in the guidance document the FAA issued in june of last year, it states that you're meant to comply with NOTAM's even as a 'hobby aircraft', so all of the 32 miles radius would be considered a 'no-fly zone' for any UAS.
that having been said, as long as you're not buzzing the motorcade or flying within the 9/10 nautical mile class b/c airspace around lax during his arrival/departure, you could probably put something in the air without issue (assuming your firmware doesn't comply with the TFR for you).
