“Invitation: Bye, bye Bernard (HFA celebration toast),” the email to the former Clinton staffers read Wednesday, less than an hour after Sanders told supporters he was ending his campaign, according to screenshots provided by two people to the outlet.

“He’s finally gone (again!). Join for a celebratory toast if you can! And yes, you can loop,” the message continued for the event that was set for 4 p.m.

Later Wednesday, the name of the call was changed to “HFA end of primary celebration toast,” using the acronym for “Hillary for America.” By 3:30 p.m., the event had been canceled, according to BuzzFeed News.

The invitation was shared among a fraction of the campaign team, which included thousands of people by the end of the 2016 campaign. It wasn't clear who created the invitation.

According to screenshots of the invitation, the invited group included staffers who went on to work for many 2020 Democratic candidates, including former South Bend, Ind., Mayor Pete Buttigieg Pete ButtigiegBogeymen of the far left deserve a place in any Biden administration Overnight Defense: Woodward book causes new firestorm | Book says Trump lashed out at generals, told Woodward about secret weapons system | US withdrawing thousands of troops from Iraq A socially and environmentally just way to fight climate change MORE, former Vice President Joe Biden Joe BidenCast of 'Parks and Rec' reunite for virtual town hall to address Wisconsin voters Biden says Trump should step down over coronavirus response Biden tells CNN town hall that he has benefited from white privilege MORE, and Sens.

Clinton provided no comment on Sanders’s exit from the race to BuzzFeed News.

Clinton called out Sanders earlier this year in a Hulu documentary about her, saying, “He was in Congress for years. He had one senator support him. Nobody likes him. Nobody wants to work with him. He got nothing done. He was a career politician. It's all just baloney, and I feel so bad that people got sucked into it.”

Sanders responded to the criticism, telling CBS News in January, “I am sorry for what Secretary Clinton had to say. I know she said that nobody likes me, right? I mean, this is not the kind of rhetoric that we need right now when we are trying to bring the Democratic Party together to defeat the most dangerous president in American history.”

Sanders suspended his presidential bid Wednesday, telling supporters in a livestreamed address, “I wish I could give you better news, but I think you know the truth. And that is that we are now some 300 delegates behind Vice President Biden and the path to victory is virtually impossible.”

“I cannot in good conscience continue to mount a campaign that cannot win and which would interfere with the important work required of all of us in this difficult hour,” Sanders added.
