President Trump's war with Twitter is confronting social media platforms with a hard dilemma: whether to take fuller responsibility for what people say on their services, or to step back and assume a more quasi-governmental role.

The big picture: Facebook is trying to be more like a government — committing to impartiality and protecting free speech and building mechanisms for arbitration. Twitter, pushed by Trump's inflammatory messages, is opting to more aggressively enforce conduct rules on its private property, like a mall owner enforcing rules inside the gates.

Former President Obama said in a statement Friday that the death of George Floyd, an unarmed black man who was killed by a white Minneapolis police officer, "shouldn't be 'normal' in 2020 America."

What he's saying: "[W]e have to remember that for millions of Americans being treated differently on account of race is tragically, painfully, maddeningly 'normal' — whether it’s while dealing with the health care system, or interacting with the criminal justice system, or jogging down the street, or watching birds in a park."
