White House chief of staff John Kelly, a U.S. Secret Service agent and the U.S. military aide in charge of the so-called nuclear football were involved in a skirmish with Chinese security officials during President Donald Trump's visit to Beijing in November, a report said Sunday.

News website Axios, quoting five sources familiar with the events, reported that the incident occurred on Nov. 9 as Trump and his team visited Beijing's Great Hall of the People.

It said the row began when the U.S. military aide carrying the nuclear football attempted to enter the Great Hall but was blocked by Chinese security officials.
