In a reversal of one of his own administration's policies, President Trump signed an executive order Wednesday that temporarily allows migrant families who have come to the U.S. illegally to stay together. Bob Carey served as the director of Office of Refugee Resettlement during the Obama administration, the federal agency responsible for caring for children who are separated from their families. Carey spoke to CBS News about how the Trump administration's "zero tolerance" policy will affect America's reputation.
