Three of Donald Trump's security staff sacked amid claims of 'improper conduct' with Asian women on White House trip

Three US servicemen have been axed from the White House security team amid allegations of “improper conduct” with foreign women during President Trump’s trip to Asia this month.

They reportedly broke curfew to fraternize with women in Vietnam. The three army non-commissioned officers, who worked for the White House Communications Agency, have been reassigned, the Washington Post reported.

Military bosses today refused to give details. “We are aware of the incident and it is under investigation,” said Pentagon spokesman Mark Wright.

US service personnel are required to report any contacts with foreign individuals to ensure their interactions do not compromise national security.

The men were in sensitive positions in a department that prevents snooping on presidential communications.

They could face discipline or court martial and risk losing their security clearances. Mr Trump, who returned from his 12-day Asia tour over a week ago, has not commented.

In August, four military staff in the same White House unit faced similar claims during a trip to Panama with vice-president Mike Pence. They were accused of taking foreign women after hours into a secure area before Mr Pence’s arrival.

In 2012, Secret Service agents were found to have hired prostitutes during a visit by Barack Obama to Colombia.

The scandal was said to have involved up to 20 women, 11 US agents and some military staff. It led the Secret Service to prohibit agents from visiting “non-reputable establishments” or drinking alcohol 10 hours before starting work.
