WASHINGTON — House Homeland Security Chairman Michael McCaul didn't mince words on colleagues — all of them fellow Republicans — who opposed a $15 billion relief package for Texans reeling from Hurricane Harvey.

"It's unconscionable to vote against something like that," said the Austin Republican.

Four Texas Republicans voted against the measure on Friday: Reps. Joe Barton of Arlington, Jeb Hensarling of Dallas, Sam Johnson of Plano, and Mac Thornberry of Clarendon.

They and other lawmakers who voted against it cited concerns with the deal struck by President Donald Trump and Democratic leaders that tied Harvey funding to a stopgap spending measure and increased the debt ceiling through December. No Democrats voted against the deal, but 90 Republicans did.

Hensarling chairs the Financial Services Committee and Thornberry chairs the Armed Services Committee. McCaul's comments — while not aimed directly at his fellow chairmen or the other Texas Republicans — exposed some friction within the Texas delegation as the state seeks unprecedented sums from Congress for storm recovery.

"That vote was a vote of conscience to help people in my state and also now in Florida," McCaul said on MSNBC Monday.

Northeastern lawmakers and leaders such as Gov. Chris Christie of New Jersey have called out a number of Texas Republicans who opposed relief money after Superstorm Sandy, calling them hypocrites now that they're pushing for Harvey aid.

McCaul said that Office of Management and Budget director Mick Mulvaney, a former South Carolina congressman and leader of fiscal conservatives in the House, told lawmakers they could not appropriate disaster relief if they did not raise the debt ceiling.

“Do you just stand on principle and vote no, and I question that principle," McCaul said, "or do you vote to help people back in your home state who are hurting really badly? When I had people dying and hurting in my home state, it was my duty and moral obligation to help them.”

McCaul added that the package was “just a down payment” to keep FEMA’s disaster relief fund afloat, with a larger supplemental aid package to come in the next few weeks.

But for many of the dissenters, the debt ceiling means did not justify the storm funding ends.

Hensarling said Congress needs a chance to offset emergency funding, with several possible cuts highlighted in Trump’s proposed budget.

“Rebuilding, as important as it is, should not go through an emergency funding process that exacerbates our dangerous and unstable national debt,” he said last week.

The Dallas Republican also criticized the missed opportunity to reform the National Flood Insurance Program, which he fought to address before its slated expiration on Sept. 30. The bill also extended the NFIP through December.

Thornberry said the measure that included the Harvey funds harms the armed forces because it continues current funding levels, which he views as too low.

Barton compared the relief funding to "a blank check" to add to the national debt.

In a statement Monday, Johnson said he voted against the bill due to the lack of offsets, a sign of "Washington's spending addiction."
