The report, in USA political news site Axios, claims that the confrontation occurred when Trump was visiting Beijing's Great Hall of the People on November 9, during a state visit to China.
A report in the United States website Axios says last November in Beijing a Chinese security official had tried to prevent Trump's military aide from carrying to Trump the briefcase of nuclear codes, popularly known as the nuclear football.
The report, which has not been confirmed, was based on five unnamed sources, according to Axios.
The "nuclear football" is a briefcase, not an actual football-but sources tell Axios that Chinese security officials acted like its carrier was trying to score a touchdown in an incident in Beijing during President Trumps' visit.
A USA official dashed into an adjoining room and informed Kelly of what was happening. The White House has yet to comment on the media report.

However, a second attempt by a Chinese security to confront the U.S. detail led to short tussle. However, a Chinese official grabbed Kelly's hand and prevented him from moving further. The last time Trump's predecessor Barack Obama visited Beijing, the White House press aide had a verbal confrontation with a Chinese security official on the tarmac of the airport.
The entire incident lasted for only a short time and the Chinese reportedly never had the nuclear football in their possession nor even touched the briefcase.
At no point did Chinese officials touch the football and the Chinese head of security later apologized, Axios reported.
This is not the first time the nuclear football has made the news under Trump.
