A trove of Hillary Clinton's private emails made public by the State Department Thursday highlighted the former secretary of state's ties to figures outside the agency she ran during President Obama's first term.

Like most previous batches of Clinton emails, the records detailed the former secretary of state's close relationship with Sidney Blumenthal, a divisive former aide and informal advisor while she worked at the State Department.

But the new emails also show the extent to which Clinton attempted to conceal her personal relationship to Blumenthal.

For example, after Blumenthal emailed her a Foreign Policy story in March 2010 about Gen. David Petraeus and prefaced the article with a personal note, Clinton asked an aide to print five copies of the email "but w/o heading from Sid."

The emails showed Clinton's interest in the political future of Rahm Emanuel, President Obama's former chief of staff and presently embattled mayor of Chicago.

"[P]ls keep me updated on all the Mayoral gossip. I can't tell yet whether Rahm will actually decide to run. So it will be a wild ride the next few months," Clinton wrote to longtime friend Betsy Ebeling in Sept. 2010.

Clinton had reached out to him while he was on vacation in Aug. 2010, just before he resigned to run for mayor of Chicago, and offered to clear her schedule if he was free for a call.

Previous email releases indicated Clinton maintained her friendship with Emanuel long after he left the White House. She has refused to join in the chorus of Democrats calling for his resignation in the wake of a Chicago police shooting scandal.

Another email indicated State Department staff members were heavily involved in a 2011 Clinton Global Initiative event. The message, written in Sept. 2011 and forwarded to Clinton's personal email address, showed 10 top State Department officials were planning to participate in the event in some capacity.

That included a dinner hosted jointly by the Clinton charity and Goldman Sachs, a longtime Clinton campaign donor.

Clinton also received a lobbying pitch from Burns Strider, who reportedly serves as an advisor to the pro-Clinton media group Correct the Record.

Strider, who founded the consulting firm Eleison Group, began an Aug. 2011 email with: "Hey Boss... I could use your assistance," and proceeded to outline the wish of two "friends" with the Ravens Group, a government service provider, who wanted to gain an audience with Undersecretary for Management Patrick Kennedy about winning lucrative contracts with the State Department.

"[H]aving this top level meeting would be invaluable for State to know and be aware of a govt contracting group with the best possible scores, results, status and cost saving measures," Strider wrote to Clinton, asking her to help the Ravens Group officials "meet the right folks."

Clinton asked an aide to print the lobbying push.

The State Department will publish roughly 2,900 pages of emails in January after falling short of a court-ordered benchmark Thursday. The original court order compelled the agency to publish 16 percent of the 55,000 total pages of Clinton emails by the end of December, but State Department officials blamed the holiday schedule and sheer volume of documents for failing to reach the threshold a federal judge laid out in May.

While the discovery of Clinton's private email use rocked the Democratic primary in the spring and summer, the former secretary of state has since recovered from the harsh scrutiny. Her poll numbers rebounded after she delivered a strong performance during an October hearing before the House Select Committee on Benghazi, when she faced multiple questions about her email network.

Law enforcement officials have given no indication that they plan to slow or stop the open FBI probe into Clinton's private email network. Authorities seized her server in August, just days after she affirmed under penalty of perjury that she had turned over all work-related emails.

FBI officials have reportedly found a way to recover some deleted emails off the private server they apprehended in August, although authorities have remained mum on whether those records were personal or work-related.

The batch of emails released Thursday contained 275 messages that had been upgraded to a classified status.
