We who value, peace and justice under law are the true conservatives. The radical right’s treasonous fascist chaos is destroying America.

During my respirator fit test today, reading the 'rainbow passage' I felt like the ending needed some editing: "There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. " Donald J. Trump, however, believes that he will find it in Greenland.

Only one environmental control can significantly limit airborne spread of measles - germicidal UV (GUV). It works for other airborne infections too (TB, influenza, and COVID-19). Find out about it and what it can do for you at our new website. Thank you to Balvi.io for support to make this possible!

"Judges must start imposing sanctions and holding [DOJ] lawyers accountable."
Opening fraudulent investigations into Governor Walz & Mayor Frey is a textbook example of prosecutorial misconduct. Judges must start imposing sanctions and holding lawyers accountable.
To every federal official participating in these shams: one day you will be held accountable.

Instead of investigating the death of Renee Good, Trump wants to investigate Governor Walz & Mayor Frey. Despicable.
This is a clear weaponization of justice against Trump's political rivals & a desperate attempt to distract from ICE's growing brutality & Trump's lawlessness.

First, they lied about what we saw on video when ICE killed Renee Good.
Now, they're politicizing the investigation by freezing out Minnesota authorities, so the full truth may never see the light of day.
They are breaking our country. We must continue demanding accountability.

@vanhollen.senate.gov Thank you for your words. John Lewis's words, #GoodTrouble never meant so much as they do today. @ivey.house.gov we need more than investigation, we need accountability. #ICEkilledGood, #TheyKilledGood
The Trump Admin continues to lie about ICE's killing of a 37-year-old mom — claiming she engaged in ‘domestic terrorism.”
They have given ICE a massive budget and allowed them to act with impunity.
I cannot & will NOT support any funding for Trump’s ICE’s operations.

She was fatally shot in South Minneapolis during a federal immigration operation. MPR reports armed Border Patrol agents showed up at Roosevelt High during dismissal and used chemical agents on bystanders. My reflections below.

Don’t be fooled: you can’t both claim this was simply the execution of an arrest warrant AND say the U.S. is now "running" Venezuela & grabbing its oil resources.
