President Donald Trump called on foreign companies on Sunday to prioritize the training and hiring of U.S. workers in industries with shortages in domestic talent. 

Trump’s comments came after the arrest of nearly 500 workers at a Hyundai car battery plant still under construction in Ellabell, Georgia, on Thursday. Of the workers arrested by Immigration and Customs Enforcement and other federal agents for being in the United States illegally, about 300 were South Korean.
