hired a press secretary who never gave a press conference during her 9 month tenure?

In July 2019, Stephanie Grisham was selected to replace Sarah Sanders as White House press secretary and communications director. She held the position for 9 months until April 2020, and was the first to hold the position without ever holding a press conference.

Grisham has been fired from previous jobs for faking expense reports and plagiarism. She also has had two DUIs, the more recent one occurring in 2016, for which she failed to appear in court before ultimately pleading guilty.

Grisham was replaced by Kayleigh McEnany, who was a vocal proponent of the Obama birther conspiracy.
