Trump signed his $147-million replacement border wall with a Sharpie

President Donald Trump visited the $147-million border wall replacement project in Otay Mesa, California, on Wednesday, and called it “amazing.”

While no new border wall has been built while Trump has been in office, the 14-mile stretch of 18- to 30-foot steel wall that replaced a decaying section on the US-Mexico border fence was completed in August.

Trump took out one of his signature Sharpies and signed a slat, saying, “You can fry an egg on that wall,” because it's designed to absorb heat.

President Donald Trump took time from his two-day fundraising trip to California to visit his beloved border wall in Otay Mesa.

He was so taken with the project that he signed one of the slats with a Sharpie.

“You can fry an egg on that wall,” Trump told the reporters and officials gathered at the fence, because it's designed to absorb heat.

The section of wall Trump visited Wednesday was a $147-million replacement project stretching 14 miles. His administration hasn't completed any new wall construction since he took office, but has replaced about 60 miles total.

Trump said he thinks they can build close to 500 miles of wall next year “depending on terrain conditions.” About 650 miles of the nearly 2,000-mile border is currently covered with barriers.

The Otay Mesa section is 18- to 30- feet high, made of steel, concrete, and rebar.

“If you think you're gonna cut it with a blowtorch that doesn't work because you hit concrete,” Trump said, adding: “It's pretty amazing.”

Trump said they had “20 mountain climbers” try and climb the wall, and this design was the hardest to climb, according to the White House pool report.

A border patrol agent told Trump: “This is the wall the agents asked for.”
