well, the back and forth in congress is getting even more toxic. let's talk now about trump ally congresswoman marjorie taylor greene. she attacked a fellow house republican, nancy mace, on twitter. >> greene called mace, quote, trash and accused her of not being a true conservative. her final zinger was misspelled. she writes, "your out of your league." i'm going to have to deduct some points for that. what did mace do to spark that ire? she condemned gop congresswoman lauren boebert for hateful remarks about ilhan omar. >> now mace has responded. what's the latest in this back and forth? >> reporter: yeah, well, the interparty feud continues to escalate this afternoon. nancy mace responded by not only correcting greene's grammar but also implying, using some colorful emojis, that greene is crazy and a clown.
