Consider this possibility......
Maybe no one in administration knew about the march or if they did, who was going to attend. The Europeans can’t stand him. They knew he would try to steal the show and it would all be about him. So no one called to tell him about it. If the US Intelligence Services knew it would be in his daily briefing. However, he rarely attends those.
There’s a high probability that the Obama Administration just didn’t know about it.
Then there’s a high prob that the CIA and NSA are useless and should be disbanded this afternoon.
Doesn’t Obama find out what’s happening on the evening news? Maybe no one watched TV for a few days or some sports event was on. ESPN probably didn’t cover it.
You mean, no one in the White House has a Yahoo page? You could not miss it, the info was there above the trending news on Bruce Jenner’s feminized transformation.
