The United Nations warned the Trump administration earlier this year that repealing ObamaCare without providing an adequate replacement would be a violation of multiple international laws, according to a new report.

Though the Trump administration is likely to ignore the U.N. warning, The Washington Post reported the Office of the U.N. High Commission on Human Rights in Geneva sent an "urgent appeal" on Feb 2.

The Post reported that the confidential, five-page memo cautioned that the repeal of the Affordable Care Act would put the U.S. “at odds with its international obligations.”

The warning was sent to the State Department and reportedly said the U.N. expressed “serious concern” about the prospective loss of health coverage for 30 million people, that in turn could violate “the right to social security of the people in the United States.”

Congressional Republicans failed in March to pass an ObamaCare replacement bill. A new proposal is emerging on Capitol Hill, but it's unclear when it might be considered and how sweeping it may be.

A spokesman for the U.N.’s human rights office in Geneva confirmed the authenticity of the letter, which was sent by Dainius Puras, a Lithuanian doctor who serves the U.N. as “Special Rapporteur on the right of everyone to the enjoyment of the highest attainable standard of physical and mental health.”

Xabier Celaya, a spokesman for the U.N., said Puras cannot comment on his ObamaCare letter until it becomes public in June.

Though the report calls out the Trump administration, there’s very little the U.N. can actually do.

According to the report, the letter sent to the Trump administration also was supposed to be shared with the majority and minority leaders in both houses of Congress -- but that did not happen.

House Minority Leader Nancy Pelosi’s office and Senate Minority Leader Charles Schumer’s office said they never received the letter, as did officials in House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell’s office. The letter from Puras did make its way to the Department of Health and Human Services, where an unnamed employee supposedly leaked it.
