Kristen Welker is a reliable stenographer for the White House. Occasionally she functions as their videographer, too, as she did in this segment. This is the end of a much longer segment where Mercedes "Mercy" Schlapp -- apparently a pal of Welker's -- was permitted to just go on and on about things, unchallenged. At the end of the interview, Welker finally decided she had a question for Schlapp about whether Trump would actually sit for an interview with Robert Mueller.
