I feel like so much of the point is being missed here. To me, it was clear based on the words he used in that tweet that he was referring to more than just Rep Omar. Telling people who were born here to go back to where they came from, in my opinion (which isn't worth anything to anyone) is racist. He is implying that non-white people are "other" or "foreign" and that to me is unacceptable. Chuck Schumer says things need to change, Nancy Pelosi complains about the state of things, no one tells them to go back to where they came from. The entire Replublican party had a pity party and B*tch fest when Obama was President, they weren't told to go back where they are from. That's the difference. Frankly Trump has spent the last 4-6 years before he was President constantly criticizing America - so who is he to tell people if they don't like it leave. There is nothing more American than using your freedom of speech to say "XYZ sucks, we need to change that". Funny to see people who wrap themselves in the flag and act like they sleep with a constitution under their pillow engaging in this kind of talk.
