The website released its ninth batch of e-mails on Sunday, more results from the apparent hack of the personal e-mail account of Hillary Clinton campaign chairman John Podesta.
As with previous disclosures, Sunday's release includes information on how Clinton's campaign can appeal to black voters, how the candidate could handle apologies, and dealings with the media.
Donald Trump and his supporters say the e-mails revealed "pay to play" relationships during Clinton's tenure as secretary of State, and talks with the Justice Department during an investigation into Clinton's use of a private e-mail server during those years.
"They let Crooked & the Gang off the hook for the crime, but it looks like the cover-up is just as bad. Unbelievable!" Trump tweeted on Sunday.
Clinton aides said the releases are the results of a computer hack. They have accused the Russians of engineering the cyber theft in an effort to help Trump's campaign.
Some Clinton aides said some of the e-mails have been doctored.
"I don’t give credence to any of these dumped documents because I don’t even know if they’re accurate," Clinton running mate Tim Kaine said on ABC's This Week. "And they are part of an effort by the Russians."
