Nobody is for open borders mack.... that is a narrative Mr T has been preaching all the time. Mr T's policies would do nothing to contain the outbreak. Barring more flights would help but that will damage his "best economy ever". Hence, he won't do it because he simply does not care.
Plus, you would have had to stop all international flights 6 weeks ago. By now you have hundreds if not thousands of carriers in the country. See Italy.
FYI, Obama deported more illegal immigrants than Mr T, all without the "brouhaha" nonsense, separating and locking up kids in cages and a medieval wall.
The difference is that the Democrats want a more open society as the US needs immigration desperately, no matter what type as their economy is very much consumer-driven. With the birth rate at very low levels, they have no choice.
Now, Mr T wants only white, educated, self-sufficient Caucasians which is a "cuckoo" fantasy. The amount of immigration the US needs will never be covered by such people as there are not sufficient who actually want to live in the US. But yeah, Mr T is good a propaganda
On another note, just this week or could be last week, we had the 100th anniversary of Hitler renaming the DAP into NSDAP (German Workers Party into National Socialist German Workers Party). Don't know if there are translations but if you read his speeches from that time you will find many parallels to Mr T.
