ORANGE, Calif. – An Egyptian student in the U.S. who posted to Facebook about killing Republican presidential frontrunner Donald Trump is now facing possible deportation.

U.S. Immigration and Customs Enforcement officers arrested Egyptian national Emad Elsayed, 23, at Universal Air Academy in El Monte, California Feb. 12 for violating terms of his visa, agency spokeswoman Virginia Kice told the Los Angeles Times.

The arrest came after Elsayed posted an article on Facebook Feb. 3 about Trump’s call to ban Muslims from entering the U.S., along with a comment that he wouldn’t mind serving a life sentence for killing The Donald. Elsayed wrote the world would thank him for the deed, CBS News reports.

U.S. Secret Service agents interviewed Elsayed the day after he made the post, then ICE returned Feb. 12 to take him into custody.

“It’s just a stupid post. You can find thousands of these every hour on Facebook and the media,” Elsayed told The Associated Press. “I don’t know why would they think I am a threat to the national security of the United States just because of a stupid post.”

Elsayed is currently jailed in Orange, Calif. awaiting a deportation hearing set for tomorrow.

“It seems like the government was not able to get a criminal charge to stick on him, so they used the immigration process to have him leave the country,” Elsayed’s attorney, Hani Bushra, told CBS News Wednesday. “The rhetoric is particularly high this election, and I just feel he got caught up in the middle.”

The Trump campaign, State Department, and Secret Service declined to discuss Elsayed’s case with the media.

Court documents allege someone at the fight school tipped off federal agents to Elsayed’s post, but Universal Air Academy owner Alex Khatib denied the charge.

“He is honestly a good student,” Khatib said. “He seemed to be a good guy.”

Bushra told the Times that when federal officials arrested his client, they forced Khatib to terminate his enrollment at the flight school, which Elsayed paid $41,000 so far to attend.

Khatib confirmed to the Associated Press he agreed to a request by federal agents to “terminate paperwork from the school that made the student eligible to study for a pilot’s license.”

The Times reports the school’s endorsement for Elsayed’s visa is critical to his ability to remain in the country, and Bushra later signed a statement indicating he would re-enroll Elsayed.

Bushra contends federal officials said they will not release Khatib from jail because his anti-Trump post is evidence he’s a danger to society.

CBS News reports:

Elsayed is from Cairo, but he said he spent much of his life in Saudi Arabia, where his father worked as a civil engineer. He came to the United States for the first time last September to attend flight school with the hope of returning to Egypt and getting a job at an airline, he said.

He said he’d like to continue his studies in the United States if the government lets him stay. If not, he will seek a refund of some of the $65,000 he has spent on his education and use it to study elsewhere.
