A fake cow that is the target of a lawsuit by a congressman is having its moment.

The Twitter account “Devin Nunes’ cow,” which professes to be “hanging out on the dairy in Iowa looking for the lil’ treasonous cowpoke,” has more than 550,000 followers as of Thursday morning, a dramatic increase from the 1,000 or so before Rep. Devin Nunes (R-Calif.) filed a lawsuit Tuesday accusing the cow account (@DevinCow), Twitter, and two other users of defamation.

Nunes’s own verified account has 396,000 followers.

Goats, cows and Devin Nunes' mom: how a Republican's Twitter lawsuit backfired
The US congressman Devin Nunes sent the Twitterverse spiraling into hilarity late on Monday with his lawsuit listing the purported crimes of Twitter users “Devin Nunes’ Mom” and “Devin Nunes’ Cow”.

In the lawsuit against Twitter and a handful of users, the California Republican claims to be the victim of vicious internet trolls, as well as the victim of selective censorship by the social media company. He is alleging that by “shadow-banning” his account, Twitter allowed for the selective amplification of “defamers” such as “Devin Nunes’ Mom” and “Devin Nunes’ Cow”.
