WASHINGTON — President Donald Trump is promising billions to help Texas rebuild from Harvey-caused epic flooding, while his Republican allies in the House are looking at cutting almost $1 billion from disaster accounts to help finance the president's border wall.

The pending reduction to the Federal Emergency Management Agency's disaster relief account is part of a massive spending bill that the House is scheduled to consider next week when lawmakers return from their August recess. The $876 million cut, which is included in the 1,305-page measure's homeland security section, pays for roughly half the cost of Trump's down payment on the U.S.-Mexico border wall that the president repeatedly promised Mexico would finance.

It seems sure that GOP leaders will move to reverse it next week as floodwaters cover Houston, the nation's fourth-largest city, and tens of thousands of Texans have sought refuge in shelters. There's only $2.3 billion remaining in federal disaster coffers.

The disaster relief cut was proposed well before Harvey. The FEMA cut is the handiwork of House Appropriations Committee Chairman Rodney Frelinghuysen, R-N.J. — the major force behind a $50 billion-plus 2013 Superstorm Sandy recovery package — and Rep. John Carter, whose home state of Texas is suffering badly from Harvey.
