On Wednesday afternoon, MSNBC anchor Katy Tur was freaking out over President Trump’s overnight Twitter typo, even to the point of absurdly warning that the commander-in-chief’s use of social media could lead to a nuclear war.

Talking to former Clinton campaign staffer Zerlina Maxwell at the end of the 1 p.m. ET hour, Tur claimed that she didn’t want to “pile on” the coverage of Trump’s “weird tweet,” but then proceeded to breathlessly ask: “...what does that say about who controls the information coming out of the White House? And what if somebody hacked into Twitter and posted a message that could have global implications? Saying something like...‘I’m going to launch nuclear weapons’?”

As Tur feared “the chain of events that something like that could set off,” Maxwell joined in the fearmongering: “Yes, this is precisely the thing that keeps me up at night, literally.” Tur interrupted and confessed: “This kept me up last night! I was up until two in the morning wondering when this tweet was going to go away.” Maxwell continued to rant: “Literally I’m afraid that Donald Trump will tweet something that will launch us into a war or a potential conflict that we won’t be able to get out of.”

Later in the 2 p.m. ET hour, Tur kept up the hand-wringing as she turned to New York Times reporter Charlie Savage: “Talk to me about the security concerns, the implications of what it means that Donald Trump has a way to communicate with America and the world that is not monitored, that is not checked?”

Savage worried: “...we are still in this unprecedented territory where normally this extraordinarily powerful person is surrounded by these layers of, you know, aides and advisers and filters to the world and Donald Trump is a very different kind of president and has insisted on keeping this unfettered check to the internet – ”

Tur repeated her wild speculation that a tweet could spark a war:

...what if his account gets hacked and somebody posts a message saying that “We are aiming nukes at North Korea”? Is there anybody that go in there and say, “Oh, my God, no, take that down”? Is anybody monitoring this account after hours in the middle of the night? How does something like this stay up for six hours?
