The Constitution says that anyone standing on US soil has all of the same rights and freedoms as a citizen, when it comes to due process. It's Republicans who are shitting on the Constitution and the laws Congress has passed in regards to claiming asylum.
Last but not least, the richest nation in the world, whose policies have lead directly to the Central American refugee crisis, is now refusing to take responsibility for helping the refugees their policies create.
Greedy, selfish and stupid - the Republican trifecta!
