President Trump is acting fast Wednesday to make changes to the way the United States vets immigrants in the wake of the tragic terrorist attack in Manhattan on Halloween, calling for Congress to end the diversity visa program by which suspect Sayfullo Saipov entered the country in the first place.

Speaking during a Cabinet meeting, Trump called the suspect an “animal” and said he should have not been allowed into the country. 

“I am today starting the process of terminating the diversity lottery program,” the president said at the White House. “We need to get rid of the lottery program as soon as possible.”

Trump will need Congress to get rid of the program, which was enacted by law in 1990 with bipartisan support.

“We’re going to quickly as possible get rid of chain migration and move to a merit program,” Trump said.

The alleged attacker, Sayfullo Saipov, came to the United States from Uzbekistan. He may have gained entry through the diversity visa program, according to media reports. The federal government has not confirmed that is the case.
