Collusion and obstruction charges have predictively fallen apart for frustrated Democrats hoping to tie those charges to their dreams of impeachment. So, with slim hopes of keeping this losing goal alive, they return to racism which will again, of course, fail.
In case no one is really paying attention, President Trump is defending being an American, our rules and laws and doesn't back off as most weasel politicians would when these agitators "happen" to be of color or an alternate race.
As we told complaining Russians, Poles, Germans, etc. who tried this crap generations ago, if you don't like America there are boats and planes leaving every day to take them to a better place. In other words, love it or leave it. That is all Trump as said.
His only mistake is confronting these extremist leftie morons (not a slur against those with mental disabilities) who are destroying the credibility of their own party all by themselves.
