A post from BelarusInside claims White House Press Secretary Katie Zachariah resigned after just five days in the role, breaking Anthony Scaramucci's 2017 record.
The post also says Donald Trump stated he advised her to step down after a difficult debut briefing. It adds that he is not rushing to name a replacement.
That is the whole claim. The post names no outlet, no document and no on-record statement, and it carries no date. Treat it as unverified until the White House or a major outlet says otherwise.
