“Denigrating federal courts and talking about 'quick' & 'strong' justice? #POTUS reveals he's dangerously uninformed,” Leahy wrote on Twitter. He linked to a statement from a human rights organization.

Leahy’s tweet comes shortly after Trump said he would consider sending 29-year-old Sayfullo Saipov, the suspect in the Tuesday truck attack that left eight people dead in lower Manhattan, to the military prison in Guantanamo Bay, Cuba.

"We need quick justice and we need strong justice — much quicker and much stronger than we have right now," Trump said Wednesday during a White House Cabinet meeting. "Because what we have right now is a joke and it's a laughing stock. And no wonder so much of this stuff takes place."

Trump "calls our courts a 'laughing stock'? That’s a false, and unserious claim. But denigrating our federal judiciary is all too serious," Leahy continued in another tweet.

“Federal courts have a track record of fairly and expeditiously dealing with terrorism suspects, having handled more than six hundred cases since 9/11,” said retired General Charles C. Krulak, in the statement released by Human Rights First that Leahy linked to. "Designating this suspect an ’enemy combatant’ does not make America safer. On the contrary: it legitimizes individuals who are nothing more than thugs and criminals by branding them as the warriors they wish to be.”

The New York Police Department's (NYPD) deputy commission for intelligence and counter-terrorism said Wednesday that the alleged attacker perpetrated the act “in the name of” the Islamic State in Iraq and Syria (ISIS).

"Based on the investigation overnight, it appears that Mr. Saipov had been planning this for a number of weeks," Miller said in a press conference. "He did this in the name of ISIS, and along with the other items recovered at the scene was some notes that further indicate that."

Saipov, who is a lawful permanent resident in the U.S., is originally from Uzbekistan, where two jihadist groups are known to operate. One of the groups, the Islamic Movement of Uzbekistan, pledged loyalty to ISIS emir Abu Bakr al-Baghdadi in 2015.
