The objections to Georgia, Michigan, Nevada certificates were only signed by members of the House of Representatives, but by no Senator, unlike those regarding Arizona and Pennsylvania.
The objection to Georgia's certificate was said (when it was raised in the joint session) to have been [intended do be] signed by some Senator(s), but Senator Loeffler (previously) said on the floor that following the Trump supporters' breaking into the Congress floor (and offices) she's no longer objecting.
I'm confused about this because I've only seen it discussed on live TV, so I'm unclear on the details. Did some Senator sign the objection to Georgia's certificate, but then got their signature "stricken", either physically or just verbally? Or did they not actually sign the objection, i.e. were they waiting until the last moment to do so and changed their mind before actually, physically signing?
