California-based In-N-Out Burger is under fire for making a $25,000 donation to the California Republican Party.

Now social media users are calling for a boycott of the popular burger chain restaurant.

What are the details?

The burger chain made a $25,000 donation to the California GOP Party, according to a public filing on the California secretary of state's website, just in time for the 2018 midterm elections.

Reporter Gabe Schneider, who was one of the first to spot the post on the secretary of state's website, shared the image Wednesday on Twitter, where it gathered an immense amount of attention.

Schneider wrote, "In-N-Out added a new item to their secret menu."

What are people saying?

Almost immediately, social media users began pushing hashtag #boycottinnout. As a result, many of the restaurant's patrons began bashing the company, with many saying that they'd never step foot in the establishment again.

One such user — California Democratic Party Chairman Eric Bauman — tweeted his support for a boycott.

Bauman wrote, "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!"

On Thursday, Us Magazine shared a story about the company's donation, saying, "In-N-Out Burger is in the midst of a PR crisis that not even a large helping of animal-style fries can fix."

Anything else?

Like the "controversial" Chick-fil-A's founder, In-N-Out Burger's late CEO, Rich Snyder, was a devout Christian and a conservative. If people look closely enough, you can see Bible verses and references to Christianity printed on cups and wrappers.

The burger chain's GOP-related donations aren't even new. According to Los Angeles Magazine, the company donated $30,000 per year to the GOP in 2016 and 2017.
