The Trump administration has launched investigations into the use of diversity initiatives in hiring and promotion at major U.S. companies, the Wall Street Journal reported on Sunday.

Google and Verizon are among a list of companies that have received Justice Department demands for documents and information about their workplace programs, the report said, citing people familiar with the investigations.

The probes are being conducted under the False Claims Act, the report said, adding that companies under scrutiny include sectors like automotive, pharmaceuticals, defense, and utilities, and some have met in person with Justice Department officials.

The False Claims Act is a federal civil law that allows the government to recover funds lost due to fraud.
