House Democrats filed a resolution Friday morning seeking to block President Trump's declaration of an emergency on the U.S.-Mexico border, which he is using to get more money to build his promised border wall after Congress declined to give him the funding he demanded. Democrats have said Trump overstepped his authority by sidestepping Congress. The Democratic-controlled House is expected to pass the resolution, but its fate is less certain in the Senate, where Republicans hold a narrow majority. Normally, Senate Majority Leader Mitch McConnell (R-Ky.) could just decline to bring legislation to the floor, but under a provision in the National Emergencies Act, the Senate has to take up the matter within 18 days after the House sends it over.
