"Walls work, it’s not my opinion," Nielsen said at the ceremony. "It’s not a tag line. It's not a political statement. It’s a fact."

The 30-foot, 2 1/2 mile long wall was built over eight months in Calexico, California.

"Looking at this, I would not attempt to climb it," Nielsen said.

"This is the wall system we are requesting Congress to fund," she later added.

During the question and answer period, Nielsen was asked about political roadblocks to constructing the wall.

"We have made the request to Congress," she said. "Whatever Congress does we are prepared to continue to focus on those areas ... But we do need the wall so we continue to ask Congress for additional funds."

In March, Trump hailed the project in Calexico as "the start" of his proposed border wall.
