Her Marine lie claimed that she was turned down for being female. Age wasn’t part of the story.
From the Daily Caller fact check:
The Washington Post’s fact-checker, Glenn Kessler, gave Hillary Clinton two Pinocchios — a rating given for significant omissions and exaggerations — for an old story she repeated this week about the time she says she applied to the Marines in 1975.
Hillary Diane Rodham was a rising legal star at the time — and would soon marry future President Bill Clinton — when she claims she went to a Marine recruiting office in Arkansas to sign up for the Corps.
But a young recruiter rejected the 26-year-old, telling her that she was too old, but that the Army might take her.
“He looks at me and he goes, ‘Um, how old are you?’ And I said ‘Well, I’m 26, I’m going to be 27.’ And he goes, ‘Well, that’s kind of old for us,’” the recruiter told her, she said Tuesday.
