Not quite.  Alexander has just made a statement phrased as a question by characterizing chloroquine and other treatments as Trump peddling "false hope" leading into the scared Americans 'question'.  I think Trump got tired of him trying to have his 15 seconds of negative while talking over him, and then talking over him after he called to another reporter for question, when his own had been answered..
Alexander was asking about the president’s effort to promote a drug, chloroquine, that is approved for other uses but that some say can mitigate the effects of the coronavirus. Dr. Anthony Fauci, a member of the president’s team, said Friday that there was no clinical evidence yet of chloroquine’s positive effects, and that the evidence was anecdotal.
Trump reiterated Friday that he was optimistic about chloroquine, largely because it had already been approved for other uses. “I am a man who comes from a very positive school. … And we’ll see how it works out, Peter. I’m not saying it will.” He added that if the drug did help, it would be a “game changer.”
Alexander then pushed back, and the following exchange ensued.
Alexander: Is it possible that your impulse to put a positive spin on things may be giving Americans a false sense of hope, and misrepresenting the preparedness right now —
Trump: No, I don’t think so. I don’t think so. No, I don’t think so. I think —

Alexander: The sale, not-yet-approved drug —
Trump: Such a lovely question. Look. It may work, and it may not work. And I agree with the doctor, what he said.  May work, may not work. I feel good about it. That’s all it is. It’s just a feeling, right, you know? I’m a smart guy. I feel good about it. And we’re gonna see — you’re gonna see soon enough. And we have certainly some very big samples of people, if you look at the people, a lot of people that are in big trouble. And this is not a drug that obviously, I think I can speak from a lot of experience, because it’s been out there for over twenty years. So it’s not a drug that you have a huge amount of danger with, it’s not like a brand new drug that’s just been created that may t have have an unbelievable, monumental effect, like kill you. We’re gonna know very soon. And I can tell you, the FDA is working very hard to get it out. Right now, in terms of malaria, if you want it, you can have a prescription. You get a prescription. And by the way — and it is very effective. It works. I have a feeling you may — and I am not being overly optimistic or pessimistic. I sure as hell think we ought to give it a try. I mean, there’s been been some interesting things happened, and some very good things. Let’s see what happens. We have nothing to lose. You know the expression, “What the hell do you have to lose?” Okay?
Alexander: So what do you say — I’ll just follow up. So what do you say Americans who are scared, though? I guess — nearly 200 dead; 14,000 who are sick; millions, as you witnessed, who are scared right now, What do you say Americans who are watching you right now who are scared? 
Trump: I say that you are a terrible reporter. That’s what I say. Go ahead. I think it’s a very nasty question, and I think it’s a very bad signal that you are putting out to the American people. The American people are looking for answers, and they’re looking for hope, and you’re doing sensationalism. And the same with NBC and Concast.  I don’t call it “Comcast,” I call it “Concast.” Let me just tell — [for] whom you work. Let me just tell you something. That’s really bad reporting. And you ought to get back to reporting instead of sensationalism. Let’s see if it works. It might, and it might not. I happen to feel good about it. But who knows? I have been right a lot. Let’s see what happens. John? — You ought to be ashamed of yourself.  Trump spars with reporters during fiery coronavirus briefing 
 
Then poor Peter went home and cried into social media, and completely omitted the "false hope" comment and insistence to keep questioning from his falsified account of the exchange.  FK these self-absorbed, TDS reporters who insist on making themselves the news instead of covering it.
