U.S. House passes $4.5 billion border aid bill

WASHINGTON (Reuters) - The U.S. House of Representatives on Tuesday approved a $4.5 billion (3.5 billion pounds)aid package to address the migrant surge along the U.S.-Mexico border, including new standards for migrants in custody following reports of poor conditions facing young children at overcrowded facilities.

The Democratic-majority House voted 230-195 to pass the measure, but its future is uncertain. The Republican-run Senate is working on its own version of the bill, and Republican President Donald Trump has vowed to veto the House legislation, with White House officials saying it would hamstring the administration's border enforcement efforts.
