POTUS left the golf tournament at 6:30 PM EDT.

A commercial flight from NJ (I went by EWR to get an idea) takes 5.5 hours.

So if his plane left at 7:00 PM EDT, he would get there around 12:30 AM EDT.

The shooting started around 1:05 AM EDT (10:05 PM PDT).

So it's possible that he was in LV at that point, maybe even just arriving.
