The user behind the “Devin Nunes’ Cow" Twitter account won't be so easily cowed by Rep. Devin Nunes' lawsuit.

The California Republican is suing Twitter and a handful of users for defamation and "shadow banning," seeking $250 million in compensatory damages and $350,000 in punitive damages.

Listed among the Twitter user defendants is “Devin Nunes’ Cow," an anonymous account that has the handle @DevinCow.

Reacting to the lawsuit, the account tweeted, "I’m not quitting my day job."

The user also encouraged a rapidly growing following to tell their followers to "copy your profile pic and write 'I am Devins Cow' as their name! Twitter already suspended Devins Mom, let’s not let them win!" by retweeting a message from "Nunes' Side Cow."

In his lawsuit, Nunes seeks to find out who is behind the Twitter accounts, requesting an injunction compell Twitter to reveal their identities, because "the corruption of American Democracy and society by intentional falsehoods, fraud and defamation must stop."

The lawsuit, filed in a Virginia state court on Monday, cites a number of mocking tweets from "Devin Nunes' Cow," including those that said Nunes' boots were "full of manure" and that Nunes is "udder-ly worthless and its pasture time to move him to prison."
