Attorney George Conway unleashed a fiery tweetstorm Wednesday in which he zapped President Trump's mental state and suggested that "someone" had to stop him.

"Someone on this runaway train needs to pull the emergency brake. Who’s it going to be?" he tweeted. He had just finished blasting Trump's psychological state, claiming that the president was "unraveling" and wouldn't get better.

"He’s becoming completely detached from reality. You can call it decompensation or psychosis, or just plain lunacy," George Conway said in one tweet. "But something needs to be done," he said in another.
