President Donald Trump called for death penalty for the New York terrorist who committed a deadly truck rampage on Tuesday.

In a tweet on Wednesday night, Trump said, “NYC terrorist was happy as he asked to hang ISIS flag in his hospital room. He killed 8 people, badly injured 12. SHOULD GET DEATH PENALTY.”

According to federal authorities, the New York terrorist named Sayfullo Saipov is a green card holder. He is a native of Uzbekistan residing in New Jersey. He entered the United States with a valid diversity immigrant visa in 2010.

Complaint filed against New York terrorist

On Wednesday, Saipov was in a wheelchair when he appeared in a federal court during his arraignment. The U.S. government charged him with providing material support for ISIS and violence and destruction of motor vehicles. He did not enter a plea.

In the complaint, FBI Special Agent Amber Tyree stated ISIS videos inspired Saipov to carry out the truck attack. He had been planning the attack over the past year. Two months ago, he decided to use a truck to inflict maximum damage to civilians.

Saipov chose Halloween for his attack because he believed that more civilians would be out for the holiday. He wanted to kill as many people as he could. Saipov yelled “Allahu Akbar” and carried a paintball gun and pellet gun when he exited the truck. He had a bag of knives but wasn’t able to reach it.

Additionally, Tyree said the New York terrorist had two cellphones. Law enforcement found around 90 videos about ISIS-related propaganda on the first cellphone. It also contains approximately 3,800 that appear to be ISIS propaganda. They found internet searches for Halloween in NYC and truck rentals in the second phone.

Furthermore, Tyree stated in the complaint that Saipov told law enforcement that he felt good about what he did. He even requested to display an ISIS flag in his room. A handwritten note with Arabic and English text was found near the scene of the crime. It included a message that the Islamic State would endure.

Saipov should be held as enemy combatant

Earlier on Wednesday, Senators John McCain and Lindsey Graham said the New York terrorist should be held as enemy combatant.

According to them, Saipov is not entitled to Miranda Rights and should be interrogated in consistent with the Law of Armed Conflict.

Graham said the United States must treat him as a soldier of the caliphate because he expressed his allegiance to ISIS.
