This week's Mainstream Media Scream finds a leading liberal TV pundit taking a page out of a Clinton-Obama advisor's anti-Donald Trump playbook. We feature MSNBC Morning Joe co-host Mika Brzezinski calling for a mental evaluation of the GOP presidential nominee.

It came Monday as the show reacted to Trump's tweet about the killing of the cousin of NBA star Dwayne Wade. In it, Trump said, "Dwayne Wade's cousin was just shot and killed walking her baby in Chicago. Just what I have been saying. African-Americans will VOTE TRUMP!"

Brzezinski said, "I actually think it's time to hear from somebody in the mental health community. To look at this person, who has been on television for months, and to give us a sense of what we have going on here. And, I'm sorry, let's stop pretending we're dealing with someone who we can completely understand. And when you see someone who you think has problems, you know it. And there's not anybody at this table who doesn't think he has some sort of problem. Let's ask the questions. Let's do this at this point. Let's set up someone and ask the questions."

Media Research Center Vice President of Research Brent Baker explains the pick: "Brzezinski long ago proved she's no independent journalist, but her hostility to Trump – talk about mental issues — has verged on the obsessive."

Rating: Five out of five screams.
