The Federal Bureau of Investigation (FBI) is investigating how the Trump administration was able to implement a sweeping health care overhaul without congressional oversight and without any public health impact assessment.

The House Oversight Committee issued a statement Thursday saying that the FBI “has requested that we obtain all documents relating to the implementation of the Affordable Care Act and its implementation that were relevant to the enactment of the AHCA, including all information related to how the implementation was achieved.”

The committee said that it “does not have the authority to compel production of documents, including those related to the Affordable Health Care Act, without congressional approval.”

The release came hours after the committee announced it would hold a public hearing on the health care rollout of the Trump-administered AHCA on June 14.

The announcement comes after the House Oversight and Government Reform Committee said that “while the committee has been briefed on the committee’s inquiry, it has not yet completed the work of interviewing witnesses.”

The announcement came hours before the committee said it would call witnesses to testify about the health bill and how it was implemented.

The White House said in a statement that the committee would not release the documents without congressional authorization.

“Congressional oversight of the implementation and implementation process of the ACA has long been a priority, and we have been working with the administration and the independent Congressional Budget Office (CBO) to ensure that the process for the ACA was fully and accurately conducted,” the statement said.
