A number of people were named as members of “Veterans for Trump” on Trump’s election website. “These veterans have pledged their support to Mr Trump in the primary, and they will be advocating for him,” a press release said.

But when the Guardian contacted several claimed Veterans for Trump members on Friday, three said they had never heard of the organisation and had not signed up as members.

“I don’t know anything about it,” said Ernie Fusi, an 88-year-old second world war veteran from Atkinson, New Hampshire. His name was among 51 “Veterans for Trump” whose details were sent out to the media and listed on Trump’s website.

“I haven’t told anyone I want to get in on that,” Fusi said. “I’m not going to do any campaigning.”
