Because a) tourists don't carry the virus but prospective immigrants do and b) there's no such thing as community spread.
The pipeline is already there because the US hasn't grounded all flights. Banning immigration while letting in tourists and business visitors and travellers in transit does the square root of one half of fuck all. Immigrants who sort out their immigration outside the US, immigrate, isolate for 14 days then start work after no symptoms are less likely to spread the virus than travellers passing through who do not isolate.
It's the typical populist bullshit targetted at the hard of thinking. Look, there's a squirrel.
