From the cited article...

...2. Adam Fox wanted to recruit 200 people to storm the Capitol, put politicians they captured on trial for treason and execute them by hanging on live television, Garbin said....

I remember seeing that a galley with a noose was set up outside the Capitol building in Washington DC during the January 6 insurrection.

Is hanging a new thing among the right-wing extremists?

I note that the so-called "trial" may be little more than a rubber stamp, as the comment I noted in #3 attributed to Mr Garbin seems to indicate that execution after the trial was a foregone conclusion.

I'll say it again, these are the self-selected people who want to solely determine the results of the elections and who governs us.
