Withheld: In addition to this specific accusation that the GOP knew about (hence, why there's a letter of '65 women'), there's also the 96% of docs from Brett's time as a Bush the Dumber toady that the GOP is holding from everyone.
Forged: Obviously, this letter of '65 women' was forged. That's why there's no signatures on the document, and why none of the '65 women' were called to testify.
Because this isn't about merely Ford anymore, this is about how the GOP actively and deliberately tried to hide information on their nominee, and quite possibly the fraudulent lengths they went to do so, like forging a document of support from '65 women'.
