Mahmoud Khalil, a Columbia student, was detained by immigration agents in March, responded to the charges against him for the first time and described his arrest "irreparable harm" to him and his family.

"I have suffered from the government's actions against me and continue to suffer," he said in a declaration included in a letter submitted by his legal team on Thursday.

"The most direct and internal injuries I've experienced are directly related to the birth of my son Dean. Instead of holding my wife's hand in the delivery room, I squatted on the floor of the detention center, whispering on the crackling phone line of her alone crackle," Khalil said. "I listened to her pain and tried to comfort her, while 70 other men slept around me. When I heard my son's first crying, I buried my face in my arms, so no one would see me crying."

His wife, Dr. Noor Abdalla, was eight months pregnant when she was arrested on March 8 at his New York apartment building. She said she had asked him to be present at birth but was rejected by U.S. immigration and customs enforcement.

Harrier said it was "destructive" to not see his family.

In his manifesto, he condemned the “weird and false” claims made by the White House and President Donald Trump. Khalil was deported after helping organize a pro-Palestine rally on the university campus.

He was locked up in a facility in rural Jena, Louisiana.

"There is entitled to a visa or green card to live and study in the United States of America," a spokesperson for the Department of Homeland Security said in a statement.

"When you advocate violence, glory and support for terrorists who enjoy killing Americans, harass Jews, take over buildings and defiling property, privileges should be revoked, and you should not be in this country," the statement added.

DHS said Khalil had contact visits with his wife and son before appearing in court and was given a choice to deceive himself.

The Justice Department declined to comment, and ICE did not immediately respond to a request for comment.

"It's hard to describe the humiliation and pain of emitting photos of himself from the highest level of the U.S. government, which is a partnership of inflammatory language, weird and false allegations, and a public celebration of my deportation," Khalil said in the announcement. "These are not only attacks on my character;

Khalil said his wife and family were also harassed after the administration labeled him a “U.S. foreign policy issue” and accused him of supporting Hamas. The allegations against him were false, he said, “deep racist.”

Harrier's lawyer said in the letter that his arrest damaged his reputation and "severely" undermined his pursuit of working in international diplomacy and human rights advocacy.

Khalil said he had worked as a policy consultant at Oxfam International but revoked the work.

"I am convinced that Rubio's determination, that my arrest and detention and subsequent public stigma played a major role in this decision," he said. "I am not surprised; such a role depends on your reputation."

Oxfam International did not immediately respond to a request for comment on Friday.

In another statement, Harrier's wife described her "fear of fear for our safety."

“Mahmoud’s case has affected every aspect of our lives,” she said. “My life as a Muslim woman wearing a hijab has experienced Islamophobia, but Mahmoud’s detention and ongoing cases have been amplified.
