U.S. Sen. Elizabeth Warren urged federal officials this week to clarify how the Trump administration has handled congressionally authorized funds for Puerto Rico’s hurricane recovery efforts, following reports suggesting that the president had cut off such spending and is using the government shutdown to stall further aid to the island.

The Massachusetts Democrat, who is eying a 2020 White House bid, sent a letter to Office of Management and Budget Director Mick Mulvaney and U.S. Department of Housing and Urban Development Secretary Ben Carson seeking answers on whether President Donald Trump ever ordered officials to end disaster relief funds for Puerto Rico.

The senator also requested information -- by Feb. 5 at the latest -- on the administration’s policy regarding congressionally authorized and appropriated funds for Puerto Rico’s recovery, as well as details on why officials concluded that the $600 million in House-approved nutrition assistance for the island was “unnecessary.”

Warren raised concerns about a recent Washington Post report, which suggested that Trump sought to end all emergency funds for Puerto Rico in September after wrongly hearing the island was using such aid to pay off its debt.

She also took issue with an NBC News story that found the partial federal government shutdown has halted HUD’s disbursement of billions in funding to help Puerto Rico rebuild infrastructure damaged by Hurricane Maria.

Warren, who traveled to Puerto Rico Tuesday as part of her presidential exploratory process, said she is “particularly concerned” about the shutdown’s impact on the island’s recovery efforts.

The senator argued that the administration’s “refusal to provide this funding, which will go to ‘the restoration of damaged and destroyed homes, businesses and infrastructure,' is directly at odds with HUD’s own ‘Contingency Plan for Possible Lapse in Appropriations'" that requires the agency to continue disbursing Community Development Block Grants and certain other grants during a shutdown.

“Given the president’s reported orders to his senior staff to eliminate Puerto Rico’s disaster recovery funding, this failure to provide congressionally approved funds raises serious concerns that HUD is using the shutdown as a pretext for withholding funds from Puerto Rico," she wrote in her letter.

NBC noted that while HUD’s contingency plan states that disaster recovery assistance programs cannot be stopped during a government shutdown, Puerto Rico’s program was technically not approved at the time federal funding ran out.

Warren further questioned why OMB opposed a $600 million grant for disaster nutrition assistance, which the senator argued could help Hurricane Maria survivors who faced food insecurity after the storm.

She argued that such reported actions “appear to reveal that President Trump either does not care about or does not understand the needs of the Puerto Rican people and the federal laws that govern assistance to the U.S. citizens who live on the island.”

In addition to the letter, the senator doubled down on her criticism of the Trump administration’s response to hurricane recovery efforts on the island during a 2020 organizing event in San Juan.

Contending that “Puerto Rico has not been treated with respect,” Warren offered that it’s “time to change that” in Washington.

The Democrat, who led a delegation of Massachusetts lawmakers to tour the island last year, recently renewed her push for an independent, “9/11-style” commission to examine the Trump administration’s response to Hurricanes Irma and Maria in Puerto Rico.

She has also called on Congress to pass legislation that would provide longer-term housing supports to hurricane evacuees and others impacted by natural disasters.
