President Donald Trump on Thursday responded to a question about the brutal assault on actor Jussie Smollett with a disconnected and illogical rant about his proposed wall along the U.S.-Mexico border.

When a reporter asked Trump about the attack on Smollett, which police in Chicago are investigating as a hate crime, the president said he had seen reports about the incident and called them "horrible" before launching into a rant about undocumented immigration.

"What I think is the worst sin of all is the fact that we're allowing people to come into this country and sell drugs and human traffic and do all of these horrible things, that if we had the simplicity of a well constructed, beautiful barrier or wall, they wouldn't be able to come into our country," Trump said. "That to me is the great sin. Everybody knows it works. I watched this morning, early in the morning, somebody trying to justify walls are immoral. If walls are immoral, maybe we should take down all the walls that are built right now. You will see a mess like you've never seen before."
