Comedian Andy Samberg explained his reasons for quitting the sketch comedy show “Saturday Night Live” 12 years ago, citing issues with his physical and mental health.

The 45-year-old “Brooklyn Nine-Nine” actor discussed what happened during an interview on Peacock’s “Hart to Heart.”

“For me, it was like, I can’t actually endure it anymore. But I didn’t want to leave,” Samberg told host Kevin Hart. “Physically and emotionally, like I was falling apart in my life.”

The comedian appeared on seven seasons of “SNL” between 2005 and 2012, participating in popular skits including “D*** in a Box” and “Natalie’s Rap.”

“Physically, it was taking a heavy toll on me and I got to a place where I was like I hadn’t slept in seven years basically,” Samberg told Hart, per Variety.

“We were writing stuff for the live show Tuesday night all night, the table read Wednesday, then being told now come up with a digital short so write all Thursday, all Thursday night, don’t sleep, get up, shoot Friday, edit all night Friday night and into Saturday, so it’s basically like four days a week you’re not sleeping, for seven years,” he continued. “So I just kinda fell apart physically.”

The comedian went on to say being a cast member on “SNL” had similarities to being a professional athlete. “It’s this high pressure thing,” Samberg said. “Your adrenaline goes through the roof. You know, there’s parallels. You have to perform under pressure in front of people.”

He admitted to being nervous about leaving despite having so many challenges with the work. “I had talked to [fellow ‘SNL’ star Amy] Poehler and other people that had already gone. I was like, once I go, when I have an idea, I can’t just do it,” he said. “The craziest thing about working there is once you get going, if you’re just in the shower and you have an idea that s— can be on television in three days, which is the most intoxicating feeling.”

Samberg said it was even more of a challenge when the “SNL” producers didn’t want him to leave.

“They told me straight up, ‘We prefer you would stay,’ and I was like, oh, that makes it harder,” he said. “But I just was like, I think to get back to a feeling of like mental and physical health, I have to do it. So I did it and it was a very difficult choice.”

Major Democratic donors have informed Future Forward, which has been a pro-Biden political action committee, that they will freeze $90 million in donations if the president remains in the presidential race, according to The New York Times.

The Times, citing “two people who have been briefed on the conversations,” reported that the frozen contributions include eight-figure donations from multiple people. According to the Times, one donor said Future Forward approached him multiple times about a contribution following Biden’s disastrous debate, but the donor said he and others are “holding off.”

A Future Forward adviser reportedly said the Super PAC expected donors who had paused contributions to unfreeze them once the Democrats resolved the uncertainty surrounding Biden’s nomination. The potential blow to Biden’s campaign comes just hours after Biden sought to assuage fears surrounding his mental and physical capabilities by holding a rare solo press conference on Thursday.

While most analysts agreed that Biden performed better during his hourlong press conference, which took place after he gave remarks at a NATO summit, than he did during his debate against former President Donald Trump, the presser appeared to do little to assure Democrats about his re-election chances. During the summit and the press conference, Biden committed multiple verbal blunders, including calling Trump his vice president and referring to Ukrainian President Volodymyr Zelensky as “President Putin.”

Biden, however, reiterated that he is committed to staying in the race, even as a growing number of Congressional Democrats have publicly called for him to step aside. Along with lawmakers and, reportedly, some major donors, a handful of celebrities have also publicly called on the president to end his campaign and allow for another candidate to take his place atop the ticket.

Actor George Clooney, who hosted a massive Hollywood fundraiser for Biden last month, wrote an op-ed in The New York Times earlier this week, saying, “[T]he Joe Biden I was with three weeks ago at the fund-raiser was not the Joe ‘big F-ing deal‘ Biden of 2010. He wasn’t even the Joe Biden of 2020. He was the same man we all witnessed at the debate.”

Leftist author Stephen King and filmmaker Michael Moore have also called on Biden to step aside.

Democrats have reportedly held private meetings on Capitol Hill throughout the past week to discuss how the party will move forward with the questions swirling on Biden’s mental ability. Former President Barack Obama and former House Speaker Nancy Pelosi (D-CA), who are still viewed as major voices within the Democratic Party, reportedly talked privately and expressed concerns about Biden’s candidacy.

The Democratic Party Convention, where Biden is set to officially be nominated as the party’s presidential nominee, will be held in Chicago on August 19-22.
