The Sheetz convenience store chain has been hit with a lawsuit by federal officials who allege the company discriminated against minority job applicants.

Sheetz Inc., which operates more than 700 stores in six states, discriminated against Black, Native American and multiracial job seekers by automatically weeding out applicants whom the company deemed to have failed a criminal background check, according to U.S. officials.

President Joe Biden stopped by a Sheetz for snacks this week while campaigning in Pennsylvania.

The Equal Employment Opportunity Commission filed suit in Baltimore against Altoona, Pennsylvania-based Sheetz and two subsidary companies, alleging the chain’s longstanding hiring practices have a disproportionate impact on minority applicants and thus run afoul of federal civil rights law.

Sheetz said Thursday that it “does not tolerate discrimination of any kind.”

“Diversity and inclusion are essential parts of who we are. We take these allegations seriously. We have attempted to work with the EEOC for nearly eight years to find common ground and resolve this dispute,” company spokesperson Nick Ruffner said in a statement.
