President Trump quickly seized on Tuesday's deadly attack in New York to promote immigration restrictions and to criticize his chief Democratic rival, New York Sen. Charles E. Schumer.
Trump first demanded the cancellation of the green card lottery program that allowed suspected attacker Sayfullo Saipov to enter the country.
The lottery program, created during the George H.W. Bush administration, was meant to allow individuals to enter the United States from countries that had low levels of immigration at that time. It had particular support from Irish American and Italian American groups, which have long had large immigrant populations in New York, and was backed by Schumer, then a member of the House, as well as Republicans from the New York area.
