OK - there was a supposed security threat. In addition, it seems there was something else- a paramour, donor, hidden visitor, medical isssue which they want to keep hidden, who knows what? VERY weird behavior.
My local news at 6pm central, reported that a small aircraft had crossed into restricted airspace near Camp David. It was told to land, and escorted by military planes to the designated landing area.
Meantime, marine 1 was diverted, and converted to a motorcade. How stupid of the W.H. press team to make up a stupid story about the weather, when it was perfectly clear that there was no significant bad weather.
