His first stop on Tuesday was in San Diego County to see the eight prototypes for his proposed border wall, even though questions remain about how the wall will be paid for. All eight models are between 18 to 30 feet high and 30 feet long. Four are made of concrete, while the others are made of alternate materials.
Trump was briefed on lessons learned from the prototypes' construction and met with border agents and officers to ask what they need, said Jonathan Hoffman, Homeland Security spokesman.
The president is determined to fulfill his campaign promise and will not be swayed by California Republican lawmakers concerned the wall is a waste of money, White House spokeswoman Sarah Huckabee Sanders told reporters Monday.

She declined to say whether Trump would pick a winning prototype during his visit.
