The e-mail exchange is a notably political departure from the general tone and contents of the 222 pages of e-mails released Friday, which primarily dealt with day-to-day happenings at the State Department. The Affordable Care Act was signed into law in March 2010, months before Tanden's exchange with Clinton. Tanden herself left the administration in February of that year.
It is unclear whether Pear, a reporter at the New York Times, met with Tanden.
Tanden also remarked that a proposal to open the Federal Employees Health Benefits (FEHB) Program to all Americans was initially proposed by Clinton during her first bid for the presidency, crediting her with giving the idea to Obama’s then-Chief of Staff Rahm Emanuel.
"My assumption is that Rahm gave them your idea as a substitute for the public plan, which didn't have the votes,” Tanden wrote. “I know that was all top secret, but I'm wondering if I should give Robert some hint of this only because it was a linchpin to moving the bill."
Clinton personally wrote Tanden in October 2011 to congratulate her on becoming president of the Center for American Progress.
"Dear Neera, I am so happy for you, for CAP and for the progressive agenda we both care so much about," Clinton wrote. "...If I can ever help--now or when I become a 'former'--please just ask."
