I found Rep. Jim Jordan's historical comments interesting. I didn't know (or remember) about Dem objections to Trump's electors in January of 2017. He was correct. Only Dem House members signed on, tho. No Senators objected. Here's the transcript: https://www.congress.gov/congressional-record/2017/01/06/house-section/article/H185-8

Without any Senators objecting, Biden (who was presiding), had to deny debate under the applicable rules:

Rep. SJ Lee objected, unsuccessfully:

Actually, SJ Lee is from Texas, so I guess this was her objection here:

Nancy Pelosi supported the objection effort in spirit, but noted that it could not succeed.

After the 2004 election, Senator Boxer joined in an objection to Ohio's electors and forced a two hour debate.

So these kinds of objections to electors in Congress are not unprecedented at all, and those saying otherwise are just historically wrong. Unfortunately because of this year's trespassing, vandalism and violence, the peaceful objectors in Congress suffer from bad optics.
