Extremism researchers and journalists (including me) warned the company in emails, on the phone, and to employees' faces after the last terror attack that the next one would show signs of YouTube radicalization again, but the outcome would be worse. I was literally scoffed at. https://t.co/z0OPqfJJw6

The only time Donald Trump says “I don’t know enough about it yet to comment” is when a white supremacist has murdered people.

Otherwise, nobody knows more about *anything* than Donald.pic.twitter.com/vH9o5tX0Ln

New: Mueller may not be done with Manafort yet. Court documents and pre-sentence hearings that dealt with the breach of his plea deal suggest that prosecutors might have more ammunition to go after him on matters that go “to the heart” of the Russia probe. https://t.co/aXl3TiJuBO
