Mr. Schiff asked in his letter whether the underlying conduct involved "the president or those around him".
While the president works on his talking points, the intelligence community's inspector general who received the whistleblower's complaint was on Capitol Hill this morning, though the New York Times reports that his closed-door testimony hasn't gone especially well for those seeking answers.
According to Mr. Schiff's letter, the original complaint was submitted on August 12 by a member of the intelligence community who worked for the National Security Council. But Joseph Maguire, the acting director of national intelligence, has refused to disclose the particulars of the alleged incident - moving some to question whether he is overstepping his bounds by shielding the president in this way. The IG really did contact the Office of the Director of National Intelligence.
While the substance of the complaint remains unknown, the Director of National Intelligence informed Schiff it does not involve anyone or any activity tied to intelligence. Klitenic wrote that the agency is protecting the whistleblower and argued the allegation does not meet the definition of "urgent concern". The source said it seemed unlikely to have been filed by someone at the Central Intelligence Agency, because the CIA has its own inspector general. John Cornyn, R-Texas, who sits on the Senate intelligence committee, said he believes his panel may be next in line.
Atkinson is scheduled to testify Thursday.

Gantz tried to paint Netanyahu as divisive and scandal-plagued, offering himself as a calming influence and honest alternative. If polls are accurate, it could be hard for Netanyahu or Gantz to secure a parliamentary majority without Lieberman's support.
Mr. Maguire's office has told the committee that the complaint involves "potentially privileged matters", language that has raised some eyebrows on Capitol Hill.
Chairman Adam Schiff made the request after an intelligence watchdog informed Congress that a whistleblower had come forward last month.
Schiff said Tuesday evening that the committee must "move quickly" on the subject and that the committee's position is clear. "He has yet to provide the complaint in response to the committee's subpoena, so I expect him to appear on Thursday, under subpoena if necessary".
He added that he was concerned that administration officials "are engaged in an unlawful effort to protect" President Donald Trump.
His acting status has put Mr. Maguire in a hard position between a White House testing his loyalty and lawmakers demanding answers to their questions.
