WASHINGTON — The chairwoman of the U.S. Senate Appropriations Committee said Tuesday the Government Accountability Office should sue the Trump administration over its efforts to freeze or unilaterally cancel spending approved by Congress.

“I believe that GAO, which is empowered under the Impoundment and Budget Control Act of 1974 to sue in cases, should do so,” Sen. Susan Collins said. “The GAO has found seven instances in which the (impoundments) violate the act and it has standing to sue.”

Collins, R-Maine, also told reporters that she doesn’t agree with the Supreme Court’s decision last week on its emergency docket that allows the Trump administration to cancel $4 billion in foreign aid.

“I disagree with the Supreme Court’s temporary decision, but it was not a decision that delved into the merits of the case,” Collins said. “That’s yet to come.”

Collins, one of the more vocal members of her party over preserving Congress’ constitutional power of the purse, said “Well, let’s see,” when asked if she expects the GAO, a government watchdog agency, would win a lawsuit over the Trump administration impounding funds.

The GAO and White House budget office did not immediately respond to a request for comment.

Funds frozen for libraries, medical research, FEMA

Republicans in Congress have been either supportive or relatively quiet about the Trump administration’s efforts to freeze or cancel funding approved by Congress.

The GAO has cited the Trump administration for illegally impounding funding for electric vehicle charging, museums and libraries, Head Start, energy efficiency upgrades in K-12 schools, funding for medical research at the National Institutes of Health and funding for the Federal Emergency Management Agency.

Senate Appropriations Committee ranking member Patty Murray, D-Wash., released a statement earlier this week rebuking the Trump administration’s actions after the GAO released its seventh impoundment decision.

“Today, we have another stark reminder of how President Trump’s lawless assault on our spending laws is hurting real people in every part of the country—as funding is held up to address homelessness, prepare for disasters, and much more,” Murray wrote. “It is time for Republicans to join us in insisting that every last penny that is owed to the American people gets out to the American people.”
