The original source for this clip has no confirmed details in the available information, so its exact video, date and context remain unknown. What is clear is how it travels online: short name based clips from creator soundboards are saved, reposted and reused as instant reactions, detached from their first appearance. This one survives because Hillary Clinton is a widely recognised political figure and PewDiePie is a widely recognised creator name, so even a sub second reference reads instantly. That combination keeps it useful for abrupt, random humour in edited videos.
