Will Stephen Miller be the first substitute White House Press Secretary?

This market will resolve according to the listed individual who hosts the first White House Press Briefing after Karoline Leavitt goes on leave. Otherwise, this market will resolve to "No". If Karoline Leavitt's leave is not announced, this market will resolve according to the next individual excepting Karoline Leavitt who hosts a White House Press Briefing as listed on the official schedule. If Karoline Leavitt does not go on leave, or if no White House Press Briefings occur between the beginning of Leavitt's leave and May 31, this market will resolve to "Other". For the purposes of this market, if Leavitt resigns or otherwise leaves her position, it will qualify as a leave. This market refers to White House press briefings by the acting White House Press Secretary (https://rollcall.com/factbase/trump/topic/calendar/). Any press briefing by the acting White House Press Secretary will qualify, even if the host is not formally announced as the acting or interim Press Secretary. "New Media" press briefings or special briefings such as those including extra guests will be considered, so long as the acting White House Press Secretary is a listed participant. Impromptu press gaggles will not be considered for the resolution of this market; only events listed on the public schedule as briefings or announcements will qualify. This market will resolve based on footage of the next White House Press Briefing that Karoline Leavitt does not host.
