Citing U.S. agents and employees who are aware of the damage, the mail reports that smugglers use recyclable saws to cut steel and concrete sections of the wall, creating openings wide enough to carry people and drugs .  Agents told Mail that saws could cut through the scissors in minutes. Engineers told the newspaper that due to the height of the brackets, which are 18 to 30 feet high, it is easier to push the steel out of the way to cross the other side.
CNN Addressed US Customs and Border Protection. An agency spokesman declined to comment before the mail.
When a breach is found, a welding crew is sent to fix the opening, the newspaper reported.
Smugglers are also trying to hide a breakthrough in the barrier by returning the cut to the cab to its original position or using a putty that looks like the hole is fixed so they continue to use that hole, according to
But agents said to the newspaper that despite the fixing and welding of the damaged brackets, the smugglers are still returning to the same place, as the metal and concrete in the core of the pliers are already weakened.
The Post reports that some of the damage has occurred in parts where electronic sensors that detect vibrations in saws have not yet been installed.
Smugglers also have makeshift ladders to climb up and over barriers in the San Diego area, and then use hooks to hang rope ladders on the other side, according to the Post Office.
A senior administration official told the Post that the number of violations amounted to "several cases" but that the new fence "significantly increased security and deterrence" along the San Diego and El Centro sections of the border.  The promise of Trump's signature campaign was to build a wall in the US and Mexico and Mexico to pay for it. When he visited a site in San Diego in September, Trump hit the wall, saying it was "virtually impenetrable."
