(CBS News/AP) - Donald Trump Jr. took to Instagram Tuesday night to endorse his father's border wall policy, saying the evidence that a wall works is because they protect people from zoo animals.
"You know why you can enjoy a day at the zoo? Because walls work," Trump Jr., 41, wrote in his Instagram story.
President Trump has proposed erecting concrete walls and steel slats to keep undocumented immigrants out of the U.S. Trump Jr.'s post came shortly after the president's Tuesday night Oval Office address, in which he declared a "crisis" at the southern border. Democrats said he had "chosen fear."
Trump Jr. has made controversial analogies on social media before, like when he compared Syrian refugees to a bowl of Skittles, in which some of the candies are poisoned.
The president said Tuesday night that all Americans are hurt by uncontrolled illegal immigration. He says it strains public resources and drives down jobs and wages.
The president says among those hit hardest by illegal immigration are African-Americans and Hispanics, though he did not provide any evidence to back that up.
The president is trying to convince Americans that the flow of immigrants into the U.S. illegally at the southern border is a crisis.
