Donald Trump took aim at federal courts for rulings he says keep illegals out of the country. He told supporters in Phoenix that courts were holding back legal immigrants who might otherwise get jobs or medical treatment.

Some lawyers say courts have stopped lawsuits against employers because they believe courts could become political targets if Trump wins the presidency. Trump has repeatedly cited judges as enemies of his judicial nominees.
