Sen. Tom Cotton argued Wednesday that President-elect Trump has a A clear mandateA to weed out illegal immigration and reform a system to prioritize American workers over unskilled, foreign workers. “President-elect Trump now has a clear mandate not only to stop illegal immigration, but also to finally cut the generation-long influx of low-skilled immigrants that undermines American workers,” Cotton said, arguing that the immigration system skews toward the rich and powerful and their ability to bring in cheap, migrant workers in order to drive down wages.
