Our stalker pal Chuck C. Johnson got into a Twitter altercation with Talking Points Memo founder Josh Marshall last night, and in the course of the exchanges revealed some interesting new information about that John Boehner fundraiser he tried to crash in March.

As we reported, Johnson was recognized by Capitol Police at the event, and detained, frisked and questioned for several hours. But last night he confirmed for the first time that it happened because the Capitol cops saw him as a potential stalking threat.

In the following embedded timeline, notice how Chuck also tries to dodge the question of whether he was given a polygraph test at the event, before he flatly denies it; and even his denial is equivocal.

(Twitter timelines are in reverse chronological order, so you may want to start at the bottom and read up.)

Chuck vs. Boehner

So Chuck has basically admitted here that he’s on the Capitol Police radar as a potential threat. That’s why he was recognized and detained at the fundraiser, obviously — and they’re quite right to be concerned about Chuck’s erratic behavior.

This means that whenever he goes to any similar event for a high profile politician from now on, he can expect similar treatment — because once you’re on this list you never get off it. Nice work, Chuck.
