WikiLeaks on Thursday published correspondences between Barack Obama and John Podesta, who is currently Hillary Clinton’s campaign chief. The data, part of Podesta’s hacked emails obtained by WikiLeaks, show several messages sent by Podesta to Obama’s personal email address, bobama@ameritech.net, in 2008 — just days before Obama was elected as president.

All of the emails, whose authenticity is yet to be independently confirmed, are from October and November 2008. Of all the emails sent to Obama’s personal email id at the time, he only responded to one, titled: “Economic Staffing Decisions.”

In the email, responding to Podesta’s insistence on a quick decision on whether William Daley or Daniel Tarullo should run the interim economic staff team in the early days of the transition, Obama replied with a terse: “I will give you an answer on this tomorrow.” The signature on the email shows it was sent from a Blackberry.

The content of other emails show Podesta focusing on what Obama may hear about the G-20 from the outgoing president George W. Bush in the coming days and hours.

“I don't want to bug you today, but the memo pasted below concerns a possible invitation to the G-20 meeting on November 15. On the chance that President Bush would raise this with you tonight, I wanted you to be aware that it is the unanimous recommendation for your advisors that you NOT attend,” Podesta, who was then leading Obama’s transition team, wrote in an email dated Nov. 4, just minutes before most news outlets had called the election in Obama’s favor.

Thursday’s document dump is part of the over 20,000 emails stolen from Podesta. U.S. intelligence officials say Russia is behind the illegal breach, and Clinton and Podesta have even accused Moscow of trying to sway the election in Republican nominee Donald Trump’s favor.

“I’ve been involved in politics for nearly five decades,” Podesta recently said. “This definitely is the first campaign that I’ve been involved with in which I’ve had to tangle with Russian intelligence agencies, who seem to be doing everything that they can on behalf of our opponent.”
