The left often condemns President Trump’s frequent attacks on the mainstream media, but an event attended by former president Barack Obama on Friday is being shrouded in secrecy, with the media and attendees being ordered to not report a word of what takes place during the “conversation with Obama.”

The Boston Globe reported Friday that Obama is scheduled to participate in a Sports Analytics Conference hosted by the Massachusetts Institute of Technology, at the Boston Convention and Exhibition Center, where he will reportedly “discuss his time in office and the next chapter of his life.” But sharing or reporting on the contents of the event is strictly forbidden.

An e-mail sent to those heading to the venue for the “conversation with Obama” reads like a line from the movie “Fight Club”: The first rule of seeing the former commander-in-chief is don’t talk about seeing the former-commander-in-chief.

During Obama’s panel, photography; video recording; streaming; and social media-posting, including on Twitter, Facebook, Instagram, Snapchat, and other platforms will not be permitted — “without exception,” the warning spelled out.

The regulations went for after the event, too.

“Following the panel, the sharing or reporting of its contents on public platforms, including social media, will not be permitted,” the notice reads. “Those who fail to adhere to this policy will be subject to removal from the conference and denied tickets to future SSAC conferences.”

Reportedly, over 3,500 people from over 35 countries are attending, representing over 200 universities and 600 organizations.
