Joe Biden made a surprise appearance at the White House briefing — his first as president — to mark the unexpectedly good jobs report today, but in taking questions from reporters, he also expressed concerns over the upcoming election.

White House Press Secretary Karine Jean-Pierre acknowledged it was the first time Biden has appeared in the briefing room, saying "You're welcome" when questioned about the president's appearance after he left the room. This is a developing story and will be updated when more information becomes available.

President Joe Biden chose to come to the briefing room for the first time just months before the end of his presidency to tout recent economic wins.
