The Labor Department is investigating whether a subcontractor working on Donald Trump’s Old Post Office hotel underpaid employees working on the downtown D.C. project, according to The Washington Post.

A Labor spokesperson told the Post the agency is looking into whether Brentwood-based glass specialist The Craftsmen Group was paying wages below those required by federal law on government construction projects.

The investigation was first reported last week by Politico. Workers on the Pennsylvania Avenue construction site, including one Craftsmen employee, told Politico that they and others were not receiving wages mandated by the Davis-Bacon Act.
