Lest we forget, the call to come to Washington D.C. was for January 6, 2021- not January 5, or January 7.
The specific date was the date the Vice-president presided over the certification of the election with a joint session of Congress. False information had been deliberately spread that VP Pence could simply refuse to certify and thereby allow Trump to continue in power.
When the certification process started and it became clear that Pence would proceed and ratification would happen is when Trump riles up the crowd and they start to march to shut it down. It wasn't to "take selfies" - it's called election interference or seditious conspiracy.
The FBI considers it a riot. The rioters were charged and convicted under various charges mostly "obstructing, influencing, or impeding an official proceeding, or attempting to do so."
Over 1,300 people were charged and as of today over 890 people have been convicted of federal crimes. Many used the defense in court of "my president called me to come and so I did."
In August 2023, Trump himself was indicted.
In good news, in 2022, the law was changed with bipartisan support to make it clear that the VP's role is ceremonial only. And importantly, it also ensures only one slate of electors makes it to Congress because, let's remember, Republicans in several states including my own state of Arizona, tried to submit an "alternate slate." As of today, those fake electors are being prosecuted by our state attorney general, a Democrat who won her seat by only 280 votes.
So if you ask me are the Democrats proud of themselves, in my case I say Hell, yes - we came very, very close to seeing our vice-president assassinated and the U.S. becoming a dictatorship.
