You can keep whining about whatever you think you know about immigration, but if someone comes to our border and asks for asylum from some country, there is the American law on immigration that must be enforced.
Many in this forum has explained to you many times that the paperwork alone is not a quick process, years can pass, in the meantime those immigrants can stay in America while it is processed.
Now the Conservatives did come up with a new procedure to speed up that process, some say it could be a mere six month wait, it was drafted by the Republican House, and it was the first time in over a decade that anything was proposed.
But trump heard about it and told those same House Republicans to not pass it.
You might not like the American Immigration laws, but one more time these immigrants are not illegal, they are following the laws of the United States of America.
