A press secretary vacancy remains unfilled. Vance has returned to the White House briefing room. This is not the first time Vance has taken on this role, as she previously filled in for Leavitt.

Vance's prior experience in the briefing room occurred when Leavitt was on maternity leave. This happened over the summer, with Vance taking the podium twice during that time.

Further details about the current situation and Vance's role are available from the source. The circumstances surrounding the press secretary vacancy are not fully outlined in the available information.
