White House Chief of Staff John Kelly was allegedly involved in a scuffle with Chinese guards over a nuclear football. The incident occurred during a state visit to Beijing in November 2017. A Secret Service agent reportedly tackled Kelly before a Chinese guard shoved him to the ground. No one from the Chinese side of the alleged scuffle made physical contact with the football, but the head of the Chinese security detail apologized to the Americans afterwards for the misunderstanding. The Secret Service has issued a statement via Twitter saying reports about Secret Service agents tackling a host nation official are false.”]
