Trump called Chinese "tough people" who would not help Clinton up if she fell down, and continued, "They'll say 'Let her come up when she's ready.'"
Trump has attacked Clinton's health many times after the former secretary of state stumbled into a van following a 9/11 memorial ceremony last month. The Manhattan mogul portrayed Clinton as a powerless leader in a recent TV ad, among numerous attacks questioning whether Clinton has the "stamina" to serve in the White House.
Clinton fired back at Trump during the first presidential debate:
"As soon as he travels to 112 countries and negotiates a peace deal, a cease fire, a release of dissidents, an opening of new opportunities in nations around the world, or even spends 11 hours testifying in front of a congressional committee, he can talk to me about stamina."
Clinton's doctor released a follow-up statement in September showing that she is in good health and physically fit to serve as president.
