Tanden deleted some, but not all, tweets from her account lambasting prominent lawmakers like Senate Majority Leader Mitch McConnell (R-KY), Sens. Joni Ernst (R-IA), and Susan Collins (R-ME), and praising their Democratic challengers. It’s unclear when exactly Tanden deleted them, but many of the tweets were available at least until the fall, according to the Internet Archive.

“Can people on here please focus their ire on McConnell and the GOP senators who are Up This Cycle who enable him: Cory Gardner, Collins, Ernst, Cornyn, Perdue, Tillis And many more,” Tanden wrote in a since-deleted tweet from June 2019 about the seven Republican senators.

When Collins’ re-election appeared troubled, Tanden vowed to treat her challenger, Sara Gideon, “like a long lost relative” and “work hard to help her beat Susan Collins.”…

Also speaking to Hill reporters on Monday, Collins said: “I do not know her, or much about her, but I do know she is a prolific user of Twitter.”
