The latest features a newly formed group called America's Frontline Doctors. About 10 physicians, dressed in white coats with an embroidered America's Frontline Doctors logo, spoke for 45 minutes in front of the Supreme Court on Monday on a range of COVID-19 talking points, from hydroxychloroquine (HCQ) being curative to the mental health effects of lockdown outweighing the toll of the virus itself.
But none of the most vocal members have practices that would place them on the actual front lines of the COVID-19 pandemic. Some don't currently practice at all.
Two of those appearing at the Monday event are ophthalmologists, one of whom is no longer licensed.
The group's website, which according to internet records was created on July 16, was de-activated on Tuesday (though past versions can be seen on . Major social media platforms have sought to remove the video from their pages.
Late Tuesday, the group was delivering a second press conference as part of a two-day "summit."
U.S. Rep. Ralph Norman (R-S.C.) opened the first briefing by calling for schools to reopen. Austin Livingston, a spokesperson for Norman, said the congressman was invited to speak by the -- which organized the event on the Supreme Court steps -- in order to "encourage state officials to open schools."
The that the Tea Party Patriots are a part of the Save Our Country Coalition, an alliance of conservative groups formed earlier this year to end regional lockdowns. That report also said the Trump campaign tried to recruit doctors to publicly support the president in his push to reopen economies.
Jenny Beth Martin, co-founder and national coordinator of the Tea Party Patriots, spoke as part of the America's Frontline Doctors press briefing. It is not clear what relationship, if any, exists between the two groups beyond the Washington event.
So who are some of these doctors involved in this group, and what involvement have they had in the pandemic?

Stella Immanuel, MD
Immanuel is a pediatrician and minister in Houston, , with a clinic in a strip mall. During Monday's briefing, she claimed she has treated 350 COVID-19 patients with HCQ and none have died.
She said she is working on publishing her own data, then added that her data would not matter because right now people are dying when not treated with the drug.
"Everybody get on hydroxychloroquine!" she said, calling the large randomized trials that debunked the drug "fake science." She also declared that people did not need to wear masks.
Immanuel could not be reached for comment Tuesday. Her ministry's website was not operational Tuesday afternoon and a GoFundMe page that she called her "legal team" has been removed from the site. A cached version of the ministry site still stands.

Previously, Todaro wrote a "white paper" in mid-March on chloroquine as prophylaxis and treatment for COVID-19, based on published information and . Twitter has since marked it as "potentially spammy or unsafe."

Joseph Ladapo, MD, PhD
Ladapo is a physician and health policy researcher at UCLA's David Geffen School of Medicine, according to his . His primary research interests include diagnostic technology cost effectiveness and decreasing cardiovascular disease population burden. He is also an adjunct professor of population health at New York University-Langone, a spokesperson confirmed, and sees patients at Langone Medical Center.
He has cared for COVID patients at UCLA, he wrote in a Wall Street Journal editorial , though that could not yet be confirmed (A UCLA Medicine spokesperson declined to answer questions Friday and said Ladapo declined comment). On the Supreme Court steps, he said nothing about treating COVID-19 patients himself.
Ladapo has publicly called for public health and political leaders to focus on protecting hospital capacity, at the expense of making decisions based on "less meaningful metrics" such as case counts and deaths, as he wrote in a , which omitted mention of personal experience in COVID patient care.
He has supported keeping the economy open: "If political leaders and health experts want to restore their credibility and the public's confidence, they need to begin by acknowledging that politics rather than science has influenced important public-health decisions and by making accommodations for dissenting perspectives," he wrote in the later Journal editorial. "Let [citizens] enter bars, enjoy the beach, exercise at the gym, and learn in school if they choose."
In his remarks Monday, Ladapo defended the use of HCQ for COVID patients, though he did not say he personally had given it to patients. Rather, he summarized the published literature and anecdotal experience of other physicians with the drug.
While randomized control trials have not shown significant health benefits, he said observational studies have shown the drug can be effective. So he cautioned against limiting physician use of the drug: "That can't possibly be the right answer," he said.
"COVID-19 is not a moral issue," he added. "COVID-19 is a challenging, complex issue that we benefit from having multiple perspectives on."
Ladapo earned his medical degree at Harvard, according to his UCLA and NYU profiles, and completed his residency in internal medicine at Beth Israel Deaconess Medical Center in Boston.
