Asked in a wide-ranging interview Wednesday on SiriusXM's "Howard Stern Show" if she hated or was "upset" with Sanders, Clinton replied, "No, disappointed. And I hope he doesn't do it again to whoever gets the nomination."
 
"Once is enough," Clinton added. "We have to join forces."
 
"Bernie could've endorsed you quicker," Howard Stern said to Clinton.
 
"He could've. He hurt me. There's no doubt about it, he hurt me."
 
Sanders waited more than a month during the heat of the 2016 White House race to formally endorse Clinton. "It was a question of bringing the party together around a progressive agenda," Sanders said of the reason for the delay in supporting his onetime rival for the Democratic nomination in a "Today" show interview shortly after his July 2016 endorsement.
 
Clinton said little when asked about several of the 2020 Democratic White House hopefuls.

"I don't want to get in the middle," she said.
 
Stern asked Clinton about fellow Democrats and allies who would like to see her fade from the political spotlight and don't want her to run for political office again. "Do you ever just want to lay in bed and say f--- this? I'm going to go into full seclusion and they'll never hear from me again," Stern asked.
 
"First of all that would only delight my adversaries, so I would never do that," Clinton replied. "But secondly I have this unique perspective. I have a particular understanding of the Russian threat."

Stern has publicly lamented that Clinton never appeared on his satellite radio show during the 2016 White House race. 

“What if Hillary had come on and — forget politics for a second — but what if we could have talked about her humanity, why she got into public service?” Stern told "Late Show" host Stephen ColbertStephen Tyrone ColbertBolton book sells 780,000 copies in first week, set to surpass 1M copies printed Obama, Clinton join virtual celebration for Negro Leagues Bolton claps back at Colbert: You've 'really insulted me' by calling me 'naive' MORE in May.
 
“I thought that if I did an interview with Hillary that she would reach a new audience,” Stern — who was a 2016 Clinton supporter despite frequently hosting Trump as a guest on his show — said.
 
Clinton acknowledged she made a "miscalculation" when it came to handling the press in the last presidential election.
 
While Trump was a "constant presence" on television, Clinton said, "I often did not prioritize media the way I should have."
 
Clinton also addressed appearing on "Saturday Night Live" and other late-night shows while campaigning for president.
 
"When I'm watching you on 'Saturday Night Live' I know you're being a good sport because you have to show your personality, and you're self-effacing, and all this stuff," Stern, 65, told "The Book of Gutsy Women" co-author. "But it's got to be a nightmare for someone like you."
 
Calling it outside her comfort zone, Clinton — who appeared on the long-running sketch comedy show in 2015 — said she enjoyed going on "SNL" even though "it's not easy for me because I'm not a comedian by any stretch of the imagination."
 
"What I find most challenging is politics has to be entertaining to a certain extent because you've got to attract people's attention," Clinton told Stern.
 
"People have to have that personality, I get all of that. And I'm more than willing to try," she said. But, Clinton said, "What I really don't understand is how we have almost trivialized politics to the point that it's about nothing but entertainment. The coverage of it is so superficial and these are serious issues."
 
Clinton also dished on a variety of lighter topics in her more than two-hour interview with Stern, including her romance with Bill ClintonWilliam (Bill) Jefferson ClintonDavis: Supreme Court decision is bad news for Trump, good news for Vance McCain's reset: US-Vietnam relations going strong after 25 years Facebook ad boycott is unlikely to solve the problem — a social media standards board would MORE during their Yale Law School days and the time Rolling Stones guitarist Keith Richards called up her mother as a surprise birthday gift. 
 
At one point Clinton recalled her first serious boyfriend, who she was dating when she met the future commander in chief.
 
Referring to her previous boyfriend as a "Greek god," Clinton quipped with a laugh, "Contrary to what you might hear, I actually like men."
