So let's unpack a few things right up front...

1. He left California and was in DC at the hotel where the WHCD was veing held.
2. Imagine the intent he had to have in order to travel that distance all the while thinking about what he was going to do.
3. He either moved several weapons or procured them in/around DC and figured out a way to get them in proximity to the WHCD.
4. He took the time to load the weapons on to his body (to reportedly include several knives) and nobody noticed.
5. Now here is the kicker...in his hidden location he was somehow aware that the President was in the room and was seated. How/when was he aware of that part?
6. If he wasn't a guest at the WHCD and he couldn't see the President from where he was....how did he know?
7. It's not like he could go look in the room and then go load up with his gear.
8. He was supposedly a guest at the exact hotel? Like every room in that place wasn't booked full over a month in advance? In DC, on a Saturday, with the WHCD in the same hotel....have you ever booked a hotel in DC during a Major Presidential event? Good luck!!!

All of it screams that he had help from someone in DC. Someone with some serious knowledge and capabilities.

You just don't pull off something like that on a whim and without some serious reconnaissance ahead of time.
