Hundreds of pages of records from Hillary Clinton's time as secretary of state revealed unexplained discrepancies between her official calendar and her personal planner, suggesting Clinton omitted the details of meetings she took at the State Department.

The documents, obtained by the Associated Press through a Freedom of Information Act lawsuit, indicated Clinton met with nearly 100 corporate executives who have also donated extensively to her campaign and to her family's foundation.

Meeting lists showed Clinton welcomed executives who had commercial interests on her desk, raising further questions about whether the then-former and future presidential candidate took any steps to shield herself from the appearance of conflicts of interest.

Her calendar and planner highlighted differences in the way official meetings were sometimes recorded.

For example, a planning schedule released earlier among troves of Clinton's private emails noted the former secretary of state met with David Kendall, her attorney, one afternoon in June 2010. The official calendar obtained by the Associated Press listed the same event as a private meeting in the secretary's office, omitting Kendall's identity.

Clinton has come under fire for allowing the work of the Clinton Foundation to overlap with her State Department duties despite an agreement with the White House barring her from interacting with the charity while in office.

While the previously undisclosed calendars do not indicate Clinton did anything illegal, the records show she used her diplomatic perch to maintain close ties with her vast donor network.

Many corporate executives whose companies had long supported Clinton's political ambitions helped her fund the U.S. pavilion at the 2010 World's Fair in Shanghai, a pet project Clinton took up in the early days of her tenure.

Several of those executives met with Clinton at the State Department to discuss the pavilion project, according to the AP. Indra Nooyi, CEO of Pepsi, and Jeffrey Immelt, CEO of General Electric, met with Clinton in February 2010 about funding the project despite a federal law prohibiting Clinton from asking executives for donations directly.

In all, 39 of the 70 corporate donors to the pavilion project were also donors to the Clinton Foundation, and many have given to Clinton's presidential campaign.

The 1,294 pages of new records were released to the AP through a bitter court battle over Clinton-related documents. The agency censored many of the meetings under FOIA exemptions that allow the government to withhold information on the grounds of privacy or broadly-defined "internal deliberations."
