Schiff subpoenaed AT&T and Verizon for the information. Sources involved in the matter have only minimal information of exactly what Schiff did, but they believe the chairman subpoenaed a total of five phone numbers — it is not clear who each number was associated with — from which the published information was taken.

It is also not clear how much phone record information Schiff received from AT&T and Verizon that was not included in the report.

To the layman, it seems worrisome that the committee would publish phone records of the president’s lawyers — are there attorney-client issues involved? — plus a journalist — are there First Amendment issues involved? — and a member of Congress. But among insiders and experts, the concern is not that Schiff broke the law — it appears he acted legally — but that the committee majority used its its authority to walk up to the edge of propriety in a politically-charged investigation.
