“Nothing proves to me more than this experience that we need to know who’s here with us,” Home Depot Co-Founder Ken Langone said after an ISIS-inspired terrorist used one of the company’s vehicles to go on a murder spree in New York City Tuesday.

Appearing on Fox News Channel, Langone said the suspect, an immigrant from Uzekistan who legitimately rented the vehicle from Home Depot, is proof that the U.S. immigration system is endangering Americans:

“Nothing proves to me more than this experience that we need to know who’s here with us. How the hell can we just say, ‘Come on in and we don’t care how you got in here and we don’t care where you’re from or what you did or what your background was’?”

Langone said he has nothing against immigration – but, the U.S. needs to know who is immigrating to the country, and why they’re coming here:

“I’m not arguing pro or against immigration. My grandparents came here as immigrants. I think virtually everybody’s ancestors came here as immigrants. We’re a country of immigrants - but, they all came legitimately and we all knew where they came from and what they wanted to do. … “This underscores the need for us to be diligent and have a program and have an effort where people have to let us know who they are and that they came in here legitimately. “Why have borders, otherwise? I don’t understand this.”

Presented with the argument that nothing can be done to stop deadly attacks, especially by “home-grown” terrorists, Langone said the U.S. shouldn’t exacerbate the problem by refusing to properly scrutinize immigrants:
