Cummings said at the hearing that after he released a letter to White House counsel Pat Cipollone yesterday outlining Newbold's testimony and a memorandum to lawmakers, Kline agreed to testify before the committee, but not on specific issues and only on general policy.
For instance, she was concerned that Kline had approved President Trump's son-in-law and senior adviser Jared Kushner's top-secret clearance after it was rejected by two career White House security specialists.

"I know that this will not be perceived in favor of my intentions, which is to bring back the integrity of the office". We've invited them to the White House to sit down with government officials here in the administration to discuss that process.
Ingraham asked Kushner if he posed a "grave national security concern to the country", referencing both Newbold's concerns and a line from Cummings memo that calls Newbold's accounts "grave reports".
