Presumptive Democratic presidential nominee Joe Biden called out to the social media network Twitter during an interview on CNN’s Situation Room on Tuesday.

He demanded that the social network “should say when things are patently not true.” His argument came in response to President Donald Trump’s tweets about left-wing media MSNBC’s Joe Scarborough and the death of one of his interns, Lori Klausutis, during his term in Congress.

CNN’s Dana Bash asked the presumptive Dem nominee about the President’s recent Twitter activities, saying that he spent a lot of time tweeting and retweeting “outlandish” comments and conspiracy theories suggesting his critics committed murder. Bash then questioned Biden if Twitter should take action against the President of the United States.

As usual, Biden gave a barely comprehensive answer, saying, “I’m of the view that social media companies have to reexamine whether or not—for example, if you put something out saying that same outlandish thing that the president thinks, a talk show host on cable committed murder, I mean, you’d say, there’s no evidence for that at all, zero.” To summarize, he believes that social media companies like Twitter should police content posted on their sites.

Bash asked a follow-up question asking Biden if he believes Twitter should take actual action. To which Biden responded, saying that he thinks they should, especially when things are not true. “They should say so.”

Sleepy Joe is just one among the many other left-wing supporters who monitor each and every move of the President, even on social media.

Last week, MSNBC’s Mika Brzezinski went on a full meltdown on Twitter and on-air all because of the President’s tweets. Brzezinski was also referring to the President’s tweets regarding Scarborough. She attacked the President on-air, saying, “That’s sick, Donald, you’re a sick person…to put this family through this…To do this just because you’re mad at Joe because Joe got ya again today because he speaks the truth.”

After that, she went to Twitter and went on a long and messy rant, even tagging and involving Twitter’s CEO Jack Dorsey. She tagged him in several tweets calling for the banning and deleting of President Trump’s Twitter account.
