Senate Republicans are under fire from progressive advocacy groups, trade unions, and congressional Democrats for voting Thursday to confirm corporate attorney Eugene Scalia, President Donald Trump's nominee to lead the U.S. Department of Labor.

"For too long, our political system has prioritized the interests of the wealthy at the expense of regular, hardworking Americans," declared Morris Pearl, chair of the Patriotic Millionaires. "Scalia will undoubtedly be yet another stooge for rich and powerful interests at the very agency designed to curb that influence."

"Senate Republicans' decision to confirm him is an absolute betrayal to the American worker," Pearl added.

JUST IN: Antonin Scalia’s son — a corporate lawyer who has spent his entire career dismantling worker protections — will now lead the agency tasked with safeguarding America’s workforce. Because of course.lead the Labor Department. Obscene. https://t.co/KDx4M6EN4B — Bernie Sanders (@SenSanders) September 26, 2019

Warren concurred, tweeting, "This is a disgrace."

This is a disgrace. Eugene Scalia spent his career putting the interests of giant corporations ahead of American workers. I stand ready to fight back to protect worker's rights. https://t.co/Ncl0bgFjS1 — Elizabeth Warren (@ewarren) September 27, 2019

Sen. Kamala Harris (D-Calif.), a 2020 White House hopeful who voted against Scalia's confirmation, wrote on Twitter Thursday that "the last person we need in charge of protecting our labor force is someone with a record of putting corporate interests over working people."

Trump nominated Scalia in July, just days after former Labor Secretary Alex Acosta announced his resignation following mass outrage over a sweetheart deal he struck with convicted sex offender Jeffrey Epstein. In
