Comer subpoenaed O'Connor last week after the physician refused to appear voluntarily for a transcribed interview with House investigators.
O'Connor's lawyers petitioned for a delay over the weekend, however, calling the scope of the probe "unprecedented."
"We are unaware of any prior occasion on which a Congressional Committee has subpoenaed a physician to testify about the treatment of an individual patient," O'Connor's legal team wrote. "And the notion that a Congressional Committee would do so without any regard whatsoever for the confidentiality of the physician-patient relationship is alarming."
A House Oversight Committee spokeswoman called their letter a "delay tactic to stonewall the Oversight Committee's investigation."
The Tuesday letter from the White House counsel's office read, "The extraordinary events in this matter constitute exceptional circumstances warranting an accommodation to Congress. Evidence that aides to former President Biden concealed information regarding his fitness to exercise the powers of the President – and may have unconstitutionally exercised those powers themselves to aid in their concealment – implicates both Congress’ constitutional and legislative powers."
"After balancing the Legislative and Executive Branch interests, as required under the accommodation process, it is the President’s view that this presents and exceptional situation in which the congressional need for information outweighs the Executive Branch’s interest in maintaining confidentiality, especially given the Executive Branch’s own interest in determining the validity of prior executive actions," the letter said.
