Republican billionaires now control every major social media platform, Fox News, CNN, WaPo, WSJ, CBS, and 200 local news stations in 100 markets. They are creating a propaganda state that treats their misinformation as fact, and actual facts as conspiracies. This is by design.

Awful self-inflicted wound for the nation. Today our federal govt gleefully condemned thousands of kids each year to chronic hepatitis and liver cancer, by denying them a vaccine invented in America, using microbial fermentation, our least expensive and safest technology

Clarence Thomas and Samuel Alito received over $2.4 million in "unreported gifts" from conservative billionaires with business before the Supreme Court, funneled through an organization whose mission is to pack the SCOTUS with their right-wing judges. Unrig the Supreme Court.

In one of the most pathetic and humiliating moments in history, Trump just received the new inaugural FIFA Peace Prize. They literally invented a “peace prize” to keep him happy after he didn’t receive the actual Nobel Peace Prize. Beyond parody https://t.co/I1ahYRCz85
