The assassination of the Speaker of the House of the Minnesota Congress and her husband, along with the attempted assassinations of another members of that state's legislative body, was national news, reported on heavily by every significant media channel in this country. The only media channels that didn't report on it in any significance, even briefly, were those channels devoted to feeding far right conservative and Republican narratives and rage.

By the way, Speaker of the House in the Minnesota Congress is 4th in line in the chain of succession in that state's government, behind the President of the Senate, Lieutenant Governor, and Governor.

If you had no idea that the fourth most important person in a state's legislative body was assassinated with clear political motives in this country then that's a strong indicator that your selection of news sources is extremely defective and biased, and that in turn is warping your own understanding of events in this country dramatically. If you care at all about being a competent citizen of this country then you must fix that defect in your understanding and knowledge of events, and the only way to do that is to broaden your chosen sources of news away from just the few that feed you your preferred narratives like slop to a hog. Listening to only those channels that reinforce your own preferred thoughts and beliefs strips you of any agency you have.
