President Donald Trump received backlash from supporters on Thursday after he proposed legislation that would allow migrant workers who entered the United States illegally to remain.

Trump announced he was “working on legislation right now,” which would allow illegal workers to stay, telling supporters at a rally in Des Moines, Iowa, “You had cases where, not here, but just even over the years where people have worked for a farm, on a farm for 14, 15 years and they get thrown out pretty viciously and we can’t do it. We gotta work with the farmers, and people that have hotels and leisure properties too.”
