White House press secretary Jay Carney on Tuesday made an apparent dig at Republicans, demanding that more administration officials testify about Obamacare’s woes on Capitol Hill.

“We cooperate with all legitimate congressional oversight,” Carney said, seeming to brush aside many of the current inquiries coming from Republican lawmakers.

However, Carney insisted that he wasn’t dismissing GOP-backed hearings on Obamacare as illegitimate.

“I think everybody here who wasn’t born yesterday has seen questionable congressional oversight in the past,” Carney said.

Contractors responsible for implementing the Obamacare website, which Carney insisted Tuesday was “improving,” will testify Thursday before the House Energy and Commerce Committee. Health and Human Services Secretary Kathleen Sebelius declined an invite but is expected to testify next Wednesday on Capitol Hill.

House Committee on Oversight and Government Reform Chairman Darrell Issa, R-Calif., is launching an investigation into the Office of Management and Budget over the implementation of the Obamacare website.

Carney declined to weigh in on Issa, who has consistently clashed with the White House.

"Is this Chairman Issa's committee?” Carney asked reporters.

He simply added, “We'll see.”
