A top labor union announced Wednesday that it will be spending $200 million to help President Biden win reelection.

The Service Employees International Union (SEIU) announced a “massive drive” to mobilize working class voters of color in battleground states to back pro-labor candidates, including Biden. The SEIU represents about 2 million members across service industries, including the health care, property service, and public services sectors.

“This election, workers are going to vote for candidates up and down the ballot who’ve got their back,” SEIU Executive Vice President Rocio Sáenz said in a statement. “They are ready to support candidates like President Biden, who walked the picket line, took on big corporations, and invested in good, union jobs.

“Workers don’t want leaders who blame immigrants for everything while giving tax breaks to billionaires and trying to take our healthcare away,” Sáenz added.
