On Thursday, House Speaker Nancy Pelosi publicly urged the White House to change its ways on the billions in withheld aid.
"We call upon the White House to stop its unlawful withholding of funds from Puerto Rico," Pelosi said at her weekly news conference.
"The ongoing withholding of funds appropriated by Congress to Puerto Rico is illegal," the Speaker told reporters.
In 2019, Congress approved a plan which set new deadlines for the Trump Administration to release aid which had been withheld to Texas, Florida, Louisiana and Puerto Rico.
But the September deadline came and went for Puerto Rico - and billions still remain on hold.
