Liz Rogers, a spokeswoman for S.L.S., said in a statement that the company had not commented on any litigation. Jesse Guzman, the president of Ultimate Concrete, said in a phone interview Monday that he was unaware of the complaint, but denied the allegations.
“Anyone can claim what they want and that doesn’t make it right or true,” he said, adding that it was two security officers who were angry that “something didn’t go their way”.
A U.S. Customs and Border Protection spokesman Greg Davis said the agency had not commented on any litigation. “Lack of comment should not be construed as conformity or determination with any of the allegations,” he said.
One of the guards, who acted as the on-site security manager for the contractors, informed the special agent of the F.B.I. that through monthly audits of workers at the San Diego site, he found that many of the workers who worked in construction and security had not been screened or approved by Customs and Border Protection.
S.L.S., a major builder of Mr. Trump’s wall, has won more than $ 1.4 billion in contracts to work on several parts of the border. With those funds, the company is said to have allowed its subcontractor Ultimate Concrete to hire armed Mexicans and facilitate illegal border crossings that the president has been working to close.
Ultimate Concrete “built a dirt road that would allow access from the Mexican side of the border into the United States,” said the whistleblowers in the complaint. “This UK-built road appears to be the route that armed Mexican nationals illegally entered the United States.”
A S.L.S. The project manager then pressured one of the whistleblowers in July 2019 not to include information about the Mexican security forces in the reports that must be submitted to the Army Corps of Engineers.
