According to LynnwoodTimes:
Never Trump Republican and outgoing congressman Adam Kinzinger (R-IL) threatened violence against a popular cartoon cat Twitter account named @catturd2 (or commonly known as Catturd) over a Ukraine meme.
Catturd is an anonymous right-leaning satirical social media account and has slightly over 1 million followers. The account was frequently retweeted by the 45th President of the United States, Donald J. Trump. Catturd is also known for leading a #CatturdForTwitterCEO campaign on Twitter. Both Catturd and Elon Musk retweet each other’s Tweets.
Below is the tweet that triggered Rep. Kinzinger to respond with the following reply, “Literal evil. If I met you in person it would not end well… for you. Sicko. Trolls who have never done a thing in their life pretend to be patriots and laugh at real warriors.”
