WASHINGTON (AP) Top House Democrats are asking White House and agency officials for internal documents about the administration proposal to send detained migrants to "sanctuary cities."
The chairmen of three House committees sent a letter Monday to the White House and Department of Homeland Security requesting emails and other documents discussing the idea, including its legal justifications and potential implications.
The letter says it's "shocking" the administration would consider such an action "for purely political reasons."
President Donald Trump has said he wants to explore the move as part of his drive to tighten immigration laws. The proposal was twice rejected by administration officials.
Officials in sanctuary cities limit cooperation with federal authorities seeking migrants in the U.S. illegally.
They tend to be in Democratic areas.
