After spending more than six weeks at an immigration detention center in Louisiana, her lawyers call it politically motivated freedom of speech.

After arriving at the Logan International Airport in Boston, Rumeysa Ozturk told reporters on Saturday that she was happy to be back in a “very difficult” period.

"In the past 45 days, I have lost my freedom and education during a critical period of doctoral studies," she said. "But I am very grateful for all the support, kindness and care."

A federal judge ordered her release Friday, awaiting the final decision on her illegal detention.

Ozturk, 30, was detained on March 25 when immigration officials arrested her in Massachusetts, revoked her student visa and transferred her to a Louisiana detention center.

Supporters believe that Ozturk, a Fulbright scholar from Turkiye, aims to co-wrote an opinion piece in her student newspaper calling on Tufts University to recognize Israel’s war on Gaza as genocide.

The International Court of Justice is targeting Israel's genocide case. Last week, former EU foreign policy chief Josep Borrell accused Israel of committing genocide.

Ozturk joined with her lawyer and two Massachusetts Congressman, Senator Edward Markey and Representative Ayanna Pressley.

"Today, we welcome you back today, Rumeysa is a huge day," Markey said. “You have built millions of people in our country and are proud of your way of fighting.”

Ozturk's lawyer said her visa was revoked without notice and that she would not allow her to contact legal counsel for more than one day after her arrest.

Ozturk appeared on court via video on Friday, talking about her worsening health, including a severe asthma attack in detention, and her hopes of continuing her doctoral research on children and social media.

U.S. District Judge William Sessions granted Ozturk a bail saying she did not pose a flight risk or danger to the public. He found that she raised serious constitutional issues with her claim for illegal detention, including potential violations of her rights to freedom of speech and due process.

Ozturk's case highlights a practice that has become common under President Donald Trump's administration. Foreign students have been arrested and hundreds of student visas have been revoked for their pro-Palestine views.

Mahmoud Khalil, who led the protests against Israel’s war on Gaza at Columbia University in New York, was one of the first students to be detained by immigration and customs enforcement on March 8. He is still in custody.

The Trump administration is accused of blending criticism of Israel, called anti-Semitism.

A spokesman for the Department of Homeland Security had previously accused Ozturk of having no evidence to support Hamas, which has been designated by the United States as a "terrorist" organization.

Ozturk denied any misconduct and said she would continue to file a lawsuit. "I have confidence in the American justice system," she said.

Her legal battles continue in Vermont when immigration hearings are held separately in Louisiana and she may attend remotely.

Video of her arrest shows masked plainclothes officers taking her away from a street in Somerville, Massachusetts, violently and chilling on a U.S. university campus.

Her attorneys at the American Civil Liberties Union believe that her arrest and detention were illegally designed to punish her speech to be protected by the First Amendment to the U.S. Constitution and to relax others’ speeches.

Pressley, who visited Ozturk along with two other Democratic lawmakers in Massachusetts, visited her during her detention, said she was detained in "dirty, inhuman conditions" and denied proper medical services to worsen the asthma attack.

"Rumeysa's experience was not just a cruel act. It was a deliberate, coordinated attempt to intimidate, instill fear and send a fearful message to anyone who dares to oppose injustice."
