There were several video cameras in use during the briefing. One was focused on Dr. Birx as she sank further into despair at what she was hearing as the president droned on about alternative treatments for Covid-19. He suggested using heat and light, introducing light into the body through the skin, and then said that disinfectants would kill the virus. As everyone knows, there are ways of killing viruses outside of the body. Boiling water works quite well. Unfortunately, boiling water also kills human flesh very well. Trump then suggests disinfectants could be introduced into the body via injection. Watch Dr. Birx as this dangerous drivel drips from the mouth of the most powerful man on earth. This is a woman on the spot, trying very hard not to cry. Listen to the moron's words while watching her face. Weep for our country weep for our world. https://www.dailykos.com/stories/2020/4/23/1939919/-WATCH-Dr-Birx-appears-utterly-horrified-as-Trump-babbles-about-injecting-disinfectants

Last response for me - The physicians (practitioners and epidemiologists connected to my employer) are questioning how the deaths could have occurred since the drug is widely used when malaria is suspected.
There is documented cases where the drugs DID reverse the impact of the COVID virus ansd facilitated recovery in patients. (I am trying to get the abstracts on those patients now) Unless the person took well over the normal dosage, they would not have expected to see any problems if the persons didn't already have other conditions which are contradindicated for use.

I question if a person took any non-prescribed drug, that they also did other things that could have killed them. So it may not really the drug ingestion on its own that caused death. Overdose maybe or allergy to the drug, maybe ...

from the FDA who support what the president said and in fact cleared the drug for use in COVID patients says this:

From FDA site speaking of potential issues of the drug -

One example of that is heart rhythm problems, which the FDA warned today had been associated with chloroquine and hydroxychloroquine. Known side-effects of the drugs could lead to “serious and potentially life-threatening heart rhythm problems,” the agency said in a statement.

“Hydroxychloroquine and chloroquine are FDA-approved to treat or prevent malaria,” the agency said. “Hydroxychloroquine sulfate is also FDA-approved to treat lupus and rheumatoid arthritis. These medicines have not been proven safe or effective for treating COVID-19.”

Most recently, reports of heart-related illness and even death among those treated with the two medications in COVID-19 cases have been recorded in the official FDA Adverse Event Reporting System database, among other places. In some incidents, the drugs have been taken on their own; in others, they were combined with other medications, like the antibiotic azithromycin.

“These adverse events included abnormal heart rhythms such as QT interval prolongation, dangerously rapid heart rate called ventricular tachycardia and ventricular fibrillation, and in some cases, death,” the FDA cautions. “Patients who also have other health issues such as heart and kidney disease are likely to be at increased risk of these heart problems when receiving these medicines.”

It's a video. You can hear Trump's own words. If you don't like my source, find another one. He says the same thing no matter which news site you check. I also saw it live. Besides, as far as I can tell, James O'Keefe wasn't there. There were multiple cameras, and you have no reason to believe that the clip I posted was fake. Watch the others. Watch all of them you want. Given the numerous right wing news sites, watch one of their clips and see what the moron said. Listen carefully. Did you hear anything in his tone suggesting he was speaking satirically? Did you hear a reporter ask him a satirical question?
