(CNN) The chairman of the House Oversight Committee issued a stark warning Friday to White House counsel Pat Cipollone, demanding that the White House turn over documents and comply with interviews related to how the White House handled security clearances of some of the President's closest advisers.

Democratic Rep. Elijah Cummings of Maryland gave the White House counsel's office until March 4 to comply with the request.

"I am now writing a final time to request your voluntary cooperation with this investigation," Cummings said. "I ask that you begin producing all responsive documents immediately, and I request that you begin scheduling transcribed interviews with each witness identified by the Committee."

Cummings' letter comes after The New York Times reported Thursday that the President personally intervened to secure his son-in-law Jared Kushner a security clearance, despite concerns from career officials. The President had previously denied he personally intervened.

"If true, these new reports raise grave questions about what derogatory information career officials obtained about Mr. Kushner to recommend denying him access to our nation's most sensitive secrets, why President Trump concealed his role in overruling that recommendation, why General Kelly and Mr. McGahn both felt compelled to document these actions, and why your office is continuing to withhold key documents and witnesses from this Committee," Cummings wrote on Friday.
