President Naomi is a character associated with Lunime, the studio behind the Gacha series of character creator and roleplay games popular with anime style creators. Fans record and share short voice lines from these characters as reaction clips, and this questioning hmmmm became a small meme for confusion. Its appeal comes from how portable it is, fitting edits, fan videos and chat style jokes without needing context from a longer scene. The clip stays in circulation because puzzled reactions never go out of style in meme culture.
