The House Permanent Select Committee on Intelligence interviewed Mary McCord on November 1, 2017. A public transcript exists. In that record she drew a line this file will not blur.
She said that because she was a career Department of Justice employee, even as Acting Assistant Attorney General for National Security she did not have the authority by statute to sign FISA applications, and that such applications had to go to someone presidentially appointed and Senate-confirmed who held the statutory signing authority. She also discussed a Carter Page application approved in the fall of 2016 and later extended. Those are her words in an official interview. They are not a confession of a crime.
Secondary outlets later wrote that she authorized or approved Page warrants. The Washington Examiner, The Federalist, The Epoch Times (Daily Caller News Foundation), and the Daily Caller used that frame in 2021 FISC-amicus stories. That framing is labeled reporting/commentary here. The transcript distinction — review versus statutory signature — governs the Fact sentences. The Nunes memo lists Comey, McCabe, Yates, Boente, and Rosenstein as the named FBI/DOJ signers of the Page applications; it does not list McCord as a signer.
The DOJ OIG Crossfire Hurricane FISA review is institutional context. This post does not attribute specific OIG sentences to her without the report naming her in a quote. An Inspector General review is not a court.
