Republican presidential candidate Donald Trump said Wednesday that the wall he wants to build along the United States-Mexico border could be named after him. Speaking at a town hall in New Hampshire, the real estate mogul revealed details about his plan to keep undocumented immigrants from coming into the country. Trump said the wall would be made of "beautiful, nice precast plank with beautiful everything."

"I want it to be so beautiful because maybe someday they'll call it the Trump Wall. Maybe," he said, according to a Fox News transcript of the event. "So I have to make sure it's beautiful, right? I'll be very proud of that wall."

Trump has been talking up the controversial wall for weeks. He mentioned it in his campaign kickoff speech, referred to it at the first GOP debate and made it a core principle in his first policy paper released Sunday. A nation must have borders, Trump said, and Mexico should pay to create one.

Trump criticized Wednesday the barriers that currently run along the roughly 2,000-mile southern border. "It is a little fence," Trump said. "People put up a ladder that they buy at Home Depot and they jump and that's the end of it."

The candidate went on to say that the U.S. needs to erect something like the Great Wall of China, which was built between the 14th and 17th centuries along the northern frontier to keep out nomad invaders (unsuccessfully). Trump said it ensures that "nobody gets through."

Trump also suggested Wednesday that "maybe a rope" could be connected to the top of his Mexico wall, but otherwise people who climb it would not be able to get down. At the Republican debate earlier this month, he said he wouldn't mind creating a "big, beautiful door" in the wall so people could enter legally.
