WASHINGTON (Reuters) - President Donald Trump's new acting chief of Homeland Security will be under pressure to implement legally dubious solutions to an influx of migrants at the U.S.-Mexico border - policies that his predecessor either could not, or would not, deliver.
Kevin McAleenan, presently commissioner of U.S. Customs and Border Protection (CBP), will be the fourth person to helm the agency under Trump. He takes over as U.S. border officials estimated that 100,000 migrants were apprehended at the southern border in March, the highest level in a decade.
