Making the first trip of his administration to California, President Donald Trump traveled to Otay Mesa Tuesday to view prototypes of his proposed border wall, saying after the tour he prefers a barrier that allows law enforcement to see through into Mexico.
Trump has long said he wanted to visit the models himself so he can pick a victor, though the Department of Homeland Security says elements of each design are expected to be used.
Trump said the wall should have metal slats at the bottom and concrete or a blend of steel and concrete at the top.
Eight 30-foot-tall prototypes have been erected near the Mexican border, south of San Diego, to serve as models.
"I think Gov. Brown has done a very poor job running California", he said.
"There are certain areas where they are really wanting us to build a wall because people are complaining, people are pouring in". "Maybe more than that".

The agency also tweeted its plans to anticipate protests, saying it will be "available to accommodate any residents who may feel a desire to exercise their First Amendment rights". "Congress must fund the BORDER WALL & prohibit grants to sanctuary jurisdictions that threaten the security of our country & the people of our country".
"If you don't have a wall system, you're not going to have a country", he said. Renegotiation of the deal began last summer.
