Tracking who the writer is, and whether the person is still part of the internal anti-Trump resistance, is difficult when the administration has a revolving door of aides. Since the beginning of Trump’s tenure, several high-ranking officials have either resigned or were pushed out of the administration: Defense Secretary Jim Mattis, chief of staff John Kelly, Homeland Security Secretary Kirstjen Nielsen, presidential assistant Omarosa Manigault Newman, U.N. Ambassador Nikki Haley, Sessions, press secretary Sean Spicer and Communications Director Anthony Scaramucci are just a handful.

While these departed officials haven’t said whether they were part of the so-called resistance within the administration, some have spoken out against Trump or have been critical of the administration’s decisions since leaving.
