Hoda Muthana was a so-called ISIS bride, women who left their home countries to join the terror group in Syria and Iraq, where they married fighters.
Muthana made a name for herself tweeting violent calls to action from her new home in Syria, including a request for people to use pick-up trucks to ram into crowds of people on patriotic holidays.
In a March 2015 tweet, she said: "Go on drive bys, and spill all of their blood, or rent a big truck and drive all over them. Veterans, Patriots, Memorial, etc day Kill them."
She told the newspaper she was "brainwashed" and regrets her actions, and that she wants to go "home".
Kurdish forces captured Muthana in January 2019 after she deserted from the village of Susa, near the ISIS front line settlement of Baghuz, the Guardian reported.
"I was brainwashed once and my friends are still brainwashed," she said in the interview, conducted in the al-Hawl refugee camp, which houses 39,000 people.
While living under ISIS she post from the now-deleted account @ZumarulJannah. She told the Guardian her Twitter account was managed by others.
Muthana graduated from Hoover High School in 2013, and enrolled at the University of Alabama at Birmingham to read business, before fleeing the US for Syria in November 2014 under guise of going to visit Atlanta, BuzzFeed reported in 2015.
She was radicalized online, the report said, and used a phone given to her by her father to access conservative Islamic lectures online. From there she started a popular Twitter account.
She told BuzzFeed that she enrolled at the University of Alabama at Birmingham, and then pulled out to get her tuition costs money returned. She then used that money to buy a plane ticket to Turkey.
Her father told BuzzFeed: "I believe she been brainwashed. She's not that kind of girl."
Speaking to the Guardian, Muthana said: "We were basically in the time of ignorance [] and then became jihadi, if you like to describe it that way. I thought I was doing things correctly for the sake of God."
"I look back now and I think I was very arrogant. Now I'm worried about my son's future. In the end I didn't have many friends left, because the more I talked about the oppression of ISIS the more I lost friends."
When asked by the Guardian what she would say to US officials, she said: "I would tell them please forgive me for being so ignorant, and I was really young and ignorant and I was 19 when I decided to leave."
"I believe that America gives second chances. I want to return and Ill never come back to the Middle East. America can take my passport and I wouldnt mind."
ISIS was "very mind-blowing," she said. "It was like a movie. You read one book and think you know everything. I'm really traumatized by my experience. We starved and we literally ate grass."
Another woman at the al-Hawl refugee camp, Shamima Begum, 19, fled the UK to join ISIS in 2015, and also wants to return home to Britain with her newborn child.
On Sunday, US President Donald Trump tweeted : "The United States is asking Britain, France, Germany and other European allies to take back over 800 ISIS fighters that we captured in Syria and put them on trial."
"The caliphate is ready to fall. The alternative is not a good one in that we will be forced to release them ..."
He later walked back the claim, saying his decision to pull roughly 2,000 troops means other countries will have to continue the fight against them.
