On the first day of their father’s administration, Eric and Donald Trump Jr. will be glad-handing at an “Opening Day” party in Washington for hundreds of wealthy well-wishers.

Details about the bash — which is separate from the official events hosted by the Presidential Inaugural Committee — are still being worked out, the event’s organizer tell us, though he confirmed that the proceeds would go to unspecified conservation organizations.

TMZ this weekend posted an invite detailing the admission prices, including a $1 million package that included, among other perks, a private reception for 16 with newly sworn-in President Trump and a “multiday hunting and/or fishing excursion for four guests with Donald Trump Jr. and/or Eric Trump, and team.” According to the document, the event will have a “Cuff Links & Camouflage” hunting-and-fishing theme (“jeans, boots, and hats are welcome”) and country acts Toby Keith and Alabama are set to perform.

But Walter Kinzie, the head of events company Encore Live, tells us that document TMZ posted was an earlier draft and that it contains some inaccuracies. But which ones? All will be revealed soon, he says. (Update: a new invite omits the audience with Trump and the hunting/fishing trip in the $1 million tier.)

In addition to the official balls, dozens of parties are slated for inauguration weekend, from those put on by state societies (the Texas “Black Tie & Boots” is reliably a big draw) to the tongue-in-cheek DeploraBall hosted by the group Gays for Trump.
