Have right-wing extremists ever been a problem at the Congress?

Have you heard about fefe and his following?

Is that a yes? My question was not a rhetorical one.

I occasionally read his blog, but "right-wing extremist" would not be one of the words I'd use to describe his content. I know nothing about his following. IIRC he is also vaccinated so not sure where this is headed.

The last available booster shot in many places was the third shot, way back in I think 2021.

That’s “the most up to date and available booster” in many countries.

The boosters since have been often only available to healthcare workers, the elderly, or those with preexisting conditions.
