WASHINGTON — President Donald Trump is expected to sign a directive this week that will make official his plans to revamp the U.S. asylum system, part of his broader push to crack down on undocumented migrants entering the U.S. illegally.

Trump is expected to sign the directive as early as Friday morning, before leaving on a trip to Paris, administration officials said. Last week, Trump said he intends to sign a “comprehensive” executive order on the detention of apprehended migrants, including those seeking asylum status.
