When Donald Trump and Mike Pence said they'd take questions from the crowd no one expected a child to ask one, but that's exactly what happened at the Roanoke rally on Monday.

"I'm a big supporter of Trump, so is my grandmother," said 12-year-old Jacob Jones of Roanoke. He came to the rally at the Hotel Roanoke and Conference Center with his dad and younger brother. He also came with a question in mind. When he had the chance, he asked it.

"What will be the timeline on that wall you have been talking about?" Jones asked.

Donald Trump answered. "Jacob, that wall will go up so fast and so powerful and [it will be] so good looking that your head will spin. OK?" Trump said.

WDBJ7 talked to Jones after the rally. What did he think of Trump's answer? "I think that was a pretty good answer for me. I don't know about anybody else out there but that was a pretty good answer for me," Jones said.

Jones said he just wanted to know when the wall would be built. That's why he asked the question.

The 12-year-old will be heading to Stonewall Jackson Middle School in Roanoke next month.
