Singer Sia on Tuesday knocked Donald Trump for questioning Hillary Clinton's stamina during Monday's first presidential debate.

Republican nominee Trump said during the debate that his Democratic rival lacked the “looks” and “stamina” to be president.

Sia replied to Trump in a video posted on Twitter. The 33-second video, which begins with Trump's claims at the debate, races through a montage of photos representing Clinton's political career as “I've got stamina,” a line from her song The Greatest, is played on a loop.

The video ends with Clinton's reply at Monday's debate: “As soon as he travels to 112 countries and negotiates a peace deal [and] a ceasefire, he can talk to me about stamina,”

The clip ends with the hashtag #ImWithHer.
