"I think it looks fantastic - very see-through, so you're able to see the other side, which is a very important element".
Another demonstrator, Hildy Roberts, 22, said in Spanish: "We need a president who will listen to all the people".
Auto parts and medical equipment makers were among the Mexican companies considering the more expensive air cargo to avoid incurring penalties for late delivery to U.S. clients or factory closures, Luis Aguirre, the president of Mexico's manufacturing industry chamber INDEX, said late on Wednesday.
Boarding the Marine One helicopter at the White House on his way to Calexico, California, Trump said his border closing threat had succeeded in persuading Mexico to stop many would be illegal immigrants on their northward journey.
The new barrier, however, has helped already. He said Vitiello is a good man, but that the administration needs to go in a tougher direction at the border.
The White House did not respond to questions Friday about whether Trump was on board with that plan.
After threatening for days to seal the border, Trump will visit the U.S. Border Patrol Calexico Station, a crossing point between the U.S. and Mexico. However, his border closure threat alarmed politicians across the country, including in his own Republican Party, who warned of dire economic fallout.

Thursday's filing argues that in addition to depriving states of federal money they are entitled to, the president's end-run around Congress was an illegal act.
Leaders of the three countries signed the USMCA in November after more than a year of negotiations.

Trump, as he so often does, mixed fact with fiction when warning of the threat at the border.
But by Thursday, Trump's demand morphed into a tariff threat.
"The tariffs will work just like they've worked with steel", he said. While US plants could stand to benefit if tariffs are put on foreign vehicles, taxes on auto parts could have a crippling effect. The furor over family separations last summer helped to highlight the fact that families won't be detained for long in the US if they're detained at all. He has spent more than 30 years in law enforcement, starting in 1985 with the U.S. Border Patrol.
Trump has invoked other executive powers, including declaring a national emergency in an effort to secure more money for his long-promised border wall.
Those families, along with unaccompanied children, are subject to specific laws and court settlements that prevent them from being immediately sent back to their home countries.
Now, with the encouragement of an influential aide and with his re-election campaign on the horizon, Trump is looking at personnel changes as he tries to shift blame elsewhere. Congress voted to block the emergency declaration, but Trump vetoed that measure.
