Cummings is now threatening To hold Kline in contempt, which Jordan says in his letter could happen as soon as Tuesday.
"To avoid unnecessary conflict between Congress and the Executive Branch and to-escalate Chairman Cummings's orchestrated interbranch confrontation, I write to ask whether Mr. Kline would agree to appear for a voluntary transcribed interview with committee staff, "Jordan wrote, offering next Tuesday or Wednesday as options.
In a letter Friday night to Jordan, Cipollone offered to make Kline available for an interview Wednesday to answer questions about the security clearance process.
But Cipollone notes that the interview would have been "limited to White House personnel security policy and practices, consistent" with past offers to the panel, which Cummings had previously rejected. Cipollone also notes that the White House counsel has been reprimanded in the room, something that Cummings had had rejected in past discussions.
Attorney General William Barr is set to testify about the Mueller report in front of the Senate Judiciary Committee.
The move is an effort to pressure. A Cummings spokesperson could not be reached for comment.
Kline had initially offered to testify voluntarily, which Jordan alludes to be in his letter, and the GOP has been published. But the White House has objected to some lines of inquiry, "The clearing up of the subpoena from the Democratic-led committee."
