Hillary Clinton's team anticipated that her health could become a liability months before the official launch of her campaign, emails published by WikiLeaks on Sunday show.
Clinton's health was included among a list of areas where hand-picked attorneys were focusing their "self-research" efforts in December 2014 as aides prepared to announce her bid for the White House.
The detail was included among more than 12,000 emails obtained illegally from the inbox of John Podesta, Clinton's campaign chair, and released by WikiLeaks.
In the email, Huma Abedin, vice chair of the campaign, outlined the "narrow areas" of focus for her team's self-research efforts. Those areas included "taxes, health, finances/speeches, [and] family."
Abedin said the opposition research was then overseen by "HFS," likely a reference to Heather Samuelson, one of Clinton's personal attorneys. She suggested bringing David Kendall, Clinton's primary legal representative, into the process.
Samuelson accompanied Clinton to her interview with the FBI in July just before the conclusion of the investigation into her emails. Her presecence at Clinton's interview has roiled critics given the fact that she was one of five witnesses who received expansive immunity deals from the Justice Department.
Other emails released by WikiLeaks this month have contained excerpts from particularly controversial paid speeches, including several in which she called for "open trade and open borders" and praised the work of Wall Street firms.
Clinton's campaign dismissed the speculation this summer that the Democratic nominee could be harboring health problems as nothing more than conspiracy theories. After she collapsed at a Sept. 11 memorial ceremony, her staff admitted she had concealed a pneumonia diagnosis but denied that she had any underlying conditions.
WikiLeaks claims to have stolen 50,000 emails from Podesta. At its current pace, the website has enough to release a batch of Podesta's records every morning until Election Day.
Clinton and her allies have largely avoided discussing the substance of the emails, instead blaming Russia and Donald Trump's alleged ties to the Kremlin for the breach.
Roger Stone, one of the Trump insiders accused of facilitating the hack, has denied involvement. The hackers who infiltrated Podesta's inbox have not yet been identified.
