WASHINGTON (AP) — House Republicans unveiled a spending bill Saturday that would keep federal agencies funded through Sept. 30, pushing ahead with a go-it-alone strategy that seems certain to spark a major confrontation with Democrats over the contours of government spending.

While conservative House Republicans have in the past dug in and opposed such spending bills, forcing Mr. Johnson to rely on Democrats to keep the government open, President Trump called on Republicans to unite and push this measure through so he and Republicans on Capitol Hill could focus on their new budgetary and tax-cutting plans.
