MILITARY investigators are looking into whether three soldiers who worked in the White House had “improper contact” with foreign women on President Donald Trump’s recent Asia trip, The Washington Post reported yesterday.

Officials familiar with the situation told the Post that the three non-commissioned officers allegedly broke a curfew during Trump’s Vietnam visit.

The service members had been working for the White House Communications Agency, a specialised military unit that helps provide top officials with secure communications, said the Post.

Pentagon spokesman Mark Wright confirmed the investigation.

“We are aware of the incident and it is currently under investigation,” Wright told AFP, without providing additional details.

The investigation is the latest headache for US security detail accompanying top officials on overseas trips.

The Post said four troops from the same White House team faced allegations around accompanying women, stemming from a trip to Panama in August with Vice-President Mike Pence.
