Lena Dunham's new feminist newsletter, Lenny, launched Tuesday and included a lengthy interview with Hillary Clinton.

But it's not easy to schedule a sit down with the busy politician.

"I basically had to be like, 'I will cancel anything,'" Dunham tells INSIDER of how the interview came to be. "We feel busy, but when we look at her schedule, we’re people who just, like, work part-time in a gift shop."

Dunham's interview with Clinton was months in the making.

"I went in to talk to Hillary's people about offering support for the campaign and let them know about Lenny," explains Dunham. "They were really open to the idea of Hillary using it as a platform to express her thoughts on everything from your 20s to feminism to issues that are of large concern for any readership."

Eventually, "We flew to New York. We made it work on her terms, very happily," explains Lenny cofounder and "Girls" producer Jenni Konner.

Dunham and Konner say they were surprisingly nervous once they got to New York for the interview.

"I have never felt so nervous, and I was just directing it," says Konner. "I was not expecting to feel that way but she has a really intense presence, and you could feel it when she walked into the building, so yeah it was terrifying and also very out of our wheelhouse."

Adds Dunham: "You’re definitely pressed to move fast, she doesn’t have a lot of time. We were told, 'The minute she comes down start rolling, get into it, because she has places to be.'"

But once Clinton entered the room, the vibe changed.

"We weren’t expecting her to be quite as at ease as when she came downstairs," says Dunham. "She walked in, and we were expecting it to be sit down and slam those questions in, but instead she was like, 'Ladies, it’s great to see you!' And that disarmed us to the max."

"She was not politician-y at all, actually," adds Konner. "She was very warm. It was disarming, really. It felt very intimate. She was very candid with us and talked so much about the vulnerable times in her life that it felt like listening to an actual friend, which was really surprising and exciting."

"They [Clinton's team] were incredibly collaborative," says Dunham. "They weren’t controlling. They didn’t vet our questions. They really gave us a chance to have journalistic freedom."

In the interview released Tuesday, Clinton discusses everything from working odd jobs in Alaska before law school to a sexy but controversial dress she wore at the White House in 1993.
