US: US President George Bush yesterday addressed a convention of the National Guard in Las Vegas as Democrats continued to highlight questions over his own National Guard service, reports Conor O'Clery.
The Democratic National Committee released a three-minute video repeating accusations that Mr Bush used family connections to get into the Guard and out of the Vietnam War.
First Lady Laura Bush criticised the use by CBS of memos allegedly proving that Mr Bush once ignored a direct order and failed to complete his national service.
"You know, they probably are altered and they probably are forgeries, and I think that's terrible, really," she told Radio Iowa in an interview.
CBS is standing by its story despite the conclusion of many experts that the documents are fake.
Yesterday a business school professor, who taught Mr Bush at Harvard University in the early 1970s, claimed the future president told him that strings were pulled to get him into the Texas Air National Guard.
Mr Yoshi Tsurumi, a John Kerry supporter, said Mr Bush had admitted to him that in order to avoid the Vietnam draft, he had got his father's friends "to skip him through the long waiting list" and that Bush thought "that was a smart thing to do".
The White House did not respond yesterday but has previously dismissed such reports as "innuendo and rumours".
Mr Bush denied in 1999 that either he or his father sought special treatment for him.
