A close ally blasted Hillary Clinton and former President Bill Clinton for sometimes having "the worst judgement" in an email released Saturday by WikiLeaks.

In the February 2015 email, Clinton adviser Neera Tanden sent word to John Podesta, now Clinton's campaign chairman, about a Washington Post article about how big donors were unable to commit money to a major super PAC supporting Clinton's presidential campaign because she had not announced her bid yet.

With the headline "Brock/Bonner," Tanden seemed to be referencing Democratic donors David Brock and Mary Pat Bonner when she began the email with "are a nightmare."

Tanden went on to express surprise that Esprit co-founder and Clinton friend Susie Tompkins Buell had not yet pledged a money donation to Priorities USA Action, as mentioned in the Washington Post article, citing an unnamed source.

"Really, Suzie Buell isn't giving to the superpac? I wonder how that got in this story," Tanden wrote.

She added, "Sometimes HRC/WJC have the worst judgement," using the initials for Hillary Rodham Clinton and William Jefferson Clinton. Clinton announced her second presidential bid in April.

"I'll be telling mary pat later this week that we aren't renewing her contract - wish me luck!" Tanden concluded.

The email was one of 36,190 emails released by WikiLeaks so far. The group has pledged to release another 14,000 before the Nov. 8 election.
