The conference, an invite-only affair held for one week each summer since 1983, basically boils down to a billionaires confab, where titans of business and industry meet to discuss the next big thing, or finagle deals.
It's like camp, but for the super-wealthy. A photographer snapped a handful of candid shots of Kushner and Trump on-site there Thursday.
Another angle shows something interesting: Kushner is wearing a name tag.
This is particularly curious, considering Kushner's face is probably on most front pages, and home pages, across the country today -- his ties to brother-in-law Donald Trump Jr's meeting with a Russian lawyer, which Kushner also attended, have dominated headlines for the past several days.
On Thursday, House Minority Leader Nancy Pelosi and Rep. Debbie Wasserman Schultz called for Kushner's security clearance to be revoked.
But, in Sun Valley, all is sunny and casual, even with the identifiers. It's OK, though, the name tag thing seems to be pretty common for the famous-types attending the conference alongside Kushner and Trump.
Iconic fashion designer Diane von Furstenberg wore one, pinned to a $300 blouse from her own label.
Media mogul Rupert Murdoch, also a name tag.
Same for Facebook COO Sheryl Sandberg.
Jeff Bezos, Amazon founder and owner of The Washington Post, was photographed arriving for a Thursday morning session wearing his.
What, specifically, Kushner and Trump are doing at the Allen & Co conference is unclear. However, a White House official did confirm the couple's attendance to CNN, and added the pair, who work as unpaid advisers to President Donald Trump, are personally funding their travel.
The Sun Valley summit is scheduled to end on Sunday.
