IRVINE (CBS13) – In-N-Out Burger, America’s favorite burger chain, is finding itself under scrutiny over a $25,000 contribution to the California Republican Party.

As uncovered by journalist Gabe Schneider, In-N-Out Burger made the contribution this week.

The contribution has prompted California Democratic Party Chairman Eric Bauman to call for a boycott of the restaurant chain.

“Et tu In-N-Out? Tens of thousands of dollars donated to the California Republican Party… it’s time to #BoycottInNOut – let Trump and his cronies support these creeps… perhaps animal style!” Bauman tweeted.

However, it wouldn’t be the first time the company made a contribution to Republicans. According to LA Mag, In-N-Out has donated to the California GOP the past several years.

As noted by The Hill, In-N-Out has also donated to other groups – including Californians for Jobs and a Strong Economy, a political action committee known to support Democratic candidates.

In a statement released on Thursday, In-N-Out’s Executive VP Arnie Wensigner also highlighted how the company has made equal contributions to Democratic and Republican political action committees in the state.

“For years, In-N-Out Burger has supported lawmakers who, regardless of political affiliation, promote policies that strengthen California and allow us to continue operating with the values of providing strong pay and great benefits for our Associates,” Wensigner wrote.

Harry and Esther Snyder founded the burger company in Southern California back in 1948. As a reflection of their Christian beliefs, Bible citations are printed on the bottoms of In-N-Out’s packaging.
