This post commenting on the disagreement was posted yesterday. Unless I'm missing something it sounds like it's talking about the arguement with MTG over the Iron Dome, which was before MTG left her house seat.

MTG arguing her side of it back on July 2025.

Now maybe there's a more recent issue this is commenting on that I missed. To my knowledge this is the only specific event where I could see someone arguing of Leftists taking MTGs side over AOC.
