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.

The suit alleges that the cow account, as well as one called @DevinNunesMom, “repeatedly tweeted and retweeted abusive and hateful content” about the congressman in violation of Twitter user guidelines.

The surging popularity of @DevinCow brought on more puns for a case that has already given life to a parody account by Stephen Colbert.

“It’s silly but also UDDER-Ly enjoyable,” CNN commentator Ana Navarro-Cárdenas tweeted. “MILK it for all it’s worth.”

Nunes, the former chairman of the House Intelligence Committee, is seeking $250 million in damages and to unmask the identity of the users behind @DevinCow and @DevinNunesMom.

According to The Washington Post’s Deanna Paul, the suit “alleged violations of Virginia’s law against insults. It also brought claims against Twitter for conspiracy and negligence. The tech company, Nunes said, “intended to generate and proliferate false and defamatory statements” about him. Its failure to police mean tweets, puns and memes posted by accounts purporting to be his mother and cow caused him “extreme pain and suffering.”

Nunes told Fox News’s Sean Hannity that the suit is “the first of many” to come, though legal experts question its chances of success.
