Trudeau's top aide faces scrutiny over election integrity and Chinese interference.

Katie Telford, Justin Trudeau's chief of staff, faces challenges as the Canadian leader and his government deal with opposition and doubts within their own party. Telford, who has been by Trudeau's side for over a decade, is known for her big-picture thinking and shrewd negotiating skills. However, some former colleagues say her inner circle has shrunk, leading to blind spots and avoidable missteps. Despite rumors of her potential exit, Telford is expected to stay by Trudeau's side as he aims for a historic fourth consecutive election win.
