A spokesperson for @AOC says they did not report this post to police, and have asked for answers from Capitol Police: "No, not at all. But when we saw his tweets last night about being visited we asked Capitol Police to look into what happened here." https://twitter.com/queeralamode/status/1380285002357776385
Will update when I know more from Twitter and the Capitol Police
That police did show up at this person's door over a post about AOC is confirmed. The open question is who sent them and why. If AOC was actually responsible for it and denied it, Capitol Police would eagerly out her, so her denial has serious credibility.
The animosity between her and the Capitol Police after January 6 is widely known https://twitter.com/puffcrusader696/status/1380518789071175684?s=20
