Here is his DHS spokesperson explicitly asking me to quote him as an anonymous source. It is his administration's policy to offer quotes to journalists in this way - many times because the administration is contradicting something he or the WH said. https://twitter.com/realDonaldTrump/status/1249045314994081795

This email was released publicly, on the internet, by DHS as part of a records request filed by the @BrennanCenter. You can find it here. https://www.documentcloud.org/documents/6821365-VFC-4.html#document/p112/a559874

If @realDonaldTrump would like us to stop quoting anonymous administration sources, he simply has to instruct his *own staff* to go on the record with journalists. He's literally in control of this.

If I filed a FOIA with any government spokesperson for the key words "on background" or "not attributable" or "per a senior administration official" I would never get it back because there would be thousands of pages. Thousands.
