Been a topic of debate for a long time.
More presently, might be a bit loopy from sleep deprivation. Had most of my NIH grant applications withdrawn due to having "foreign components". No money going to any foreigners, mind you, but some things like blood samples getting donated to us from outside the US (where a lot of diseases tend to happen) seems to have caught some attention. So I'm peddle to the metal writing new grants so my people can feed their families. No worries, though, I'm the prettiest science guy in SoCal, so worst case I've got OnlyScientists!
