The recent WikiLeaks disclosures about US Democratic presidential candidate Hillary Clinton reveal the “shocking” calculations of her campaign and have severely hurt her credibility, says an American analyst.

“What WikiLeaks is providing, it's showing to the entire world the calculations of the Clinton campaign, some of which are shocking,” said James Bovard, a policy adviser to the Future of Freedom Foundation.

“It’s had a huge adverse impact on the credibility of the Clinton campaign with the folks who follow the WikiLeaks fairly closely,” Bovard told Press TV on Tuesday.

WikiLeaks has announced that it will release the 50,000 emails it claims it has, every day between October 8 and the Election Day on November 8.

“Unfortunately, American voters will almost certainly be left in the dark on election day,” Bovard added. “It’s typical that the biggest election frauds occur before the voting booths open and the 2016 presidential election will probably be no different.”

Newly released documents show that the State Department sought to shield Clinton from prosecution by pressuring the FBI to drop its insistence that an email on the private server she used while secretary of state contained classified information.

The FBI ultimately decided against declassifying the email's contents, despite pressure from Patrick Kennedy, the State Department’s most senior manager, according to the latest release of interview summaries from the FBI’s year-long investigation into Clinton's exchange of classified government secrets via her unauthorized server.

One FBI official, whose name is redacted from the document, told investigators that Kennedy repeatedly "pressured" the various officials at the FBI to declassify information in one of Clinton's emails.

The email was about the 2012 attack against two US government facilities in Benghazi, Libya, and included information that originated from the FBI, which meant that the agency had the authority on whether it would remain classified.

Republican presidential candidate Donald Trump has blasted Clinton’s use of the private email server, calling it a scandal that’s “worse than Watergate.”
