That is true. But the “big” info re immigration fraud hadn’t been exposed until after the rally, so it wasn’t a thing at that time.
At the rally, the focus was on Trump’s tweets about going to her native country and fixing that sh!thole.
NOW — it’s definitely “Send her back!”
Omar's immigration fraud problem has been simmering for a while. A lot of people on the right have known about it for months.
There is this article from May 20, 2019 "Ilhan Omar Becomes Subject Of Immigration Fraud Lawsuit".
And this from March 12, 2019 "Compelling evidence supports claims that Rep. Ilhan Omar committed immigration fraud"
I suspect Trump knows exactly what the situation is, and Omar's problems are just beginning. Trump is crazy like a fox.
