The National Republican Congressional Committee quickly pointed out the error. “Maybe if @AOC spent more time interacting with lawmakers and less time making coloring books, she’d recognize the other socialist Democrats in her caucus”, the NRCC wrote in a tweet, linking to Ocasio-Cortez’s post.

The oft gaffe-generating Alexandria Ocasio-Cortez was at it again Thursday as she attempted to call out "older male" Republicans for posing next to a cardboard cut-out of her, in a tweet blunder she was swift to delete.

The lawmaker wasn't a Republican, though. He was a fellow Democrat. Rep. John Yarmuth is a member of the Congressional Progressive Caucus, which Ocasio-Cortez belongs to.

"GOP: Let's pose our older male members next to cardboard cutouts of young female legislators", Ocasio-Cortez had tweeted sarcastically, linking to a tweet from the Kentucky GOP that showed Rep. John Yarmuth next to a cut-out of herself. Yarmouth is the House budget chairman, hailing from the same "House" where Ocasio-Cortez works.

.@AOC FYI, the "older male" pictured is John Yarmuth. Your colleague. And a Democrat.

​On Thursday, the Republican Party of Kentucky tweeted a photo of Rep. John Yarmuth, a Democrat from the Bluegrass State who chairs the House Budget Committee and has served in Congress since 2007.

Although Ocasio-Cortez rushed to delete the tweet, Twitter exploded in mockery.

.@AOC has deleted the tweet calling @RepJohnYarmuth Kentucky's sole Democratic member of Congress (and House Budget Co chair) one of the GOP's "older male members" but it lives on to infinity… https://t.co/7uDqdZgPoj — lesley clark (@lesleyclark) April 25, 2019

​Whether it was "GOP" in the account's name that confused her, or some other reason, Ocasio-Cortez has been on the receiving end of a backlash from conservatives, who have been revelling in spreading screengrabs of the tweet.

Socialist Rep. Alexandria Ocasio-Cortez (D-NY) thinks Rep. John Yarmuth (D-KY) is a Republican member of Congress.



It literally says in the tweet that she is quoting that Yarmuth is a Democrat.



AOC doesn't even know who her Democrat colleagues in Congress are, how embarrassing. pic.twitter.com/p9mxv2qwxw — Ryan Saavedra (@RealSaavedra) April 25, 2019

That's John Yarmuth, the lone Kentucky Democrat they're mocking in their tweet, not an older, male GOP congressman.

While some reasoned she'd done it purposefully, others offered Ocasio-Cortez some advice, with even John Yarmuth himself weighing in with a twitter response.

I was a Republican 35 years ago, but I think I have become wiser as an older, white, male Democrat. I simply wanted everyone to know I welcome @RepAOC in Kentucky, regardless of what old white male Republicans think. https://t.co/WOY7bIy6Yf — Rep. John Yarmuth (@RepJohnYarmuth) April 25, 2019

Ocasio-Cortez has been frequently publicly mocked for reported cluelessness on matters of government and a complete lack of understanding of economics.

Whether or not due to frequent media ridicule, Ocasio-Cortez earlier this month claimed that she was cutting down on use of social media and quitting Facebook, calling it a “public health risk”.
