"I think it's kind of absurd in the hours after this awful attack to be using it as a fulcrum for a debate that's been going on in Congress for completely different reasons", Representative Adam Schiff of California said on MSNBC on Wednesday.
The president wants to use this attack as an excuse to limit immigration. Police officials said witnesses recounted hearing the attacker shout "Allahu Akbar" as he exited his truck, and multiple outlets have reported police found a note pledging allegiance to Isis. "Look at him as an unlawful enemy combatant, take the time you need to develop who he is, what he did, and why; be ready to present if necessary to a federal judge your case against him being an unlawful enemy combatant".
In the immediate aftermath of the attack, the President called on Twitter for tougher immigration restrictions, saying he would "step up our already Extreme Vetting Programme" and suggesting he wanted to scrap a visa lottery system.
Trump noted during a Cabinet meeting that Saipov had entered the country through the "Diversity Visa Lottery Program" and called on Congress to "immediately" begin working to eliminate the program, which applies to countries with low rates of immigration to the U.S.
Part of the solution would be to allow Trump's travel ban for some Muslim-majority countries to go into effect, Graham said.
Sen. John McCain (R-Ariz.), who has previously been critical of Guantanamo, also called for Saipov to be held in military detention. The facility became deeply controversial during the administration of George W Bush for holding terrorism suspects indefinitely.
Mr Trump said the United States needed "far greater" punishment for such "animals".
"What we have right now is a joke and it's a laughing stock", Trump said.
While Barack Obama vowed to shutter the prison, he failed in the face of resistance from Congress. "There's no Miranda rights for somebody who kills Americans". Uber confirmed that he drove more than 1,400 trips in six months, but the company said they have removed him from the service.
Sen. Lindsey Graham (R-S.C.) said he, too, believed Saipov should be held as an enemy combatant.
