Elon Musk poked fun at Sen. Ed Markey, D-Mass., on Twitter after the Democrat demanded to know why a Washington Post reporter was able to create a verified account impersonating him.

"A @washingtonpost reporter was able to create a verified account impersonating me—I’m asking for answers from @elonmusk who is putting profits over people and his debt over stopping disinformation," Markey tweeted Friday, with a screenshot of his letter to Musk on the matter. "Twitter must explain how this happened and how to prevent it from happening again."

In his letter, Markey said the reporter was able to create the fake account and get verified by paying $8 under Musk's new rules. The senator blasted the new process as "lax" and "unacceptable."

Musk, the billionaire tech mogul who recently purchased Twitter, replied on Sunday, suggesting that the reason someone impersonated Markey's account is that his real one "sounds like a parody."

Musk followed up by asking why Markey's profile picture showed him wearing a mask.

Several pundits and progressives blasted Musk for the retort.

"He’s an elected official with constituents," former Ohio Democratic state Sen. Nina Turner tweeted, "This isn’t a game, dude."

"Always risky to attack members of congress. Especially risky with Dems assured of Senate power. Curious play by Musk here. He has many interests before Congress," Politico's Sam Stein mused.

Senior CNN political analyst Ronald Brownstein echoed the sentiment of many liberal pundits that Musk appears to be on a "right-wing" crusade.

"For only $8 a month, you can help support the lifestyle of a struggling South African billionaire who’s using his newly purchased platform to mock Democrats in the United States Congress," Keith Boykin said.

Musk has been making some major changes at the social media platform, including the firing of several top executives, including CEO Parag Agrawal, CFO Ned Segal and head of legal policy, trust, and safety Vijaya Gadde. Users can also now purchase verification for $8 per month.

In his letter, Markey demanded details on the "process" for issuing paid-for blue checkmark verifications, how it differed from the free verification process that preceded it, and how the Washington Post reporter in question was able to obtain verification of a fake account.

The senator also slammed Musk in a follow-up tweet.

"One of your companies is under an FTC consent decree," Markey said. "Auto safety watchdog NHTSA is investigating another for killing people. And you’re spending your time picking fights online. Fix your companies. Or Congress will."

Myocarditis cases hit levels two-to-three times higher in people with a second dose of the Moderna COVID-19 vaccine than the Pfizer BioNTech COVID-19 vaccine, research shows.

American College of Cardiology released a study last week that showed that males and females between 18 and 39 with the Moderna vaccine had higher rates of pericarditis and myocarditis. However, males ages 18-29 had the highest rates after receiving the second dose of Moderna.

The National Institutes of Health reports patients experience symptoms of chest pain, fever, fatigue, shortness of breath, and a rapid or irregular pulse, heart failure, shock or death.

Researchers pulled data from approximately 3 million people in British Columbia, Canada, and used participants over the age of 18 who were hospitalized for myocarditis, pericarditis, or myopericarditis within 21 days after having received a second Pfizer or Moderna between Jan. 1, 2021, and Sept. 9, 2021. The study excluded participants that had experienced myocarditis or pericarditis within one year before receiving the second dose of the COVID-19 vaccine.

“Within 21 days of the second dose, there were a total of 59 myocarditis cases, 21 after Pfizer and 31 after Moderna; and there were a total of 41 pericarditis cases: 21 after Pfizer and 20 after Moderna,” the study reads. “Researchers also looked at rates per million doses and the rate was 35.6 cases per million for Moderna and 12.6 per million for Pfizer—an almost threefold increase after Moderna shots vs. Pfizer.”

“Comparatively, rates of myocarditis in the general population in 2018, were 2.01 per million in people under age 40 and 2.2 per million in people over age 40,” the study added.

Guy Witberg, MD, MPH, a cardiologist at Rabin Medical Center in Petah-Tikva, Israel, said the study is “reassuring for vaccine safety,” adding it personalizes the approach to administering COVID-19 vaccines since further data shows myocarditis is a very rare adverse event after both vaccines.

[The study] should help put to rest ‘vaccine hesitancy’ due to concerns over cardiac adverse events,” Witberg said. “This is one of only a few direct comparisons of the two widely adopted mRNA vaccines, and its results have practical policy implications: for a substantial segment of the population suffering from cardiovascular disease.”

Moderna spokesman Luke Mircea-Willats emailed a statement to UPI saying, “mRNA-1273 has been administered to hundreds of millions of people worldwide and has been shown to be effective against both the original strain of the virus and its major variants.”

“Regulatory agencies around the world have stated that the benefits of COVID-19 mRNA vaccines significantly outweigh the risk across all age groups,” Mircea-Willats wrote. “Vaccination against COVID-19 continues to be a critical tool in overcoming the impacts of the global pandemic.”

Moderna told UPI myocarditis cases are a known but “very rare” risk associated with COVID-19 mRNA vaccines, adding, “when it does occur, cases are generally mild and resolve after a few days with treatment and rest.”

Moderna further notes population levels indicate that the risk of myocarditis after COVID-19 infection is much higher than after COVID-19 vaccination, adding it “shares all adverse events data with regulators and has a robust pharmacovigilance function, ensuring any adverse events are recorded and shared with the regulator in line with local regulations.”

The research drew mainstream media attention over the weekend.

Da’Vion Miller, 23, told NBC News that he initially experienced heart inflammation symptoms like chest pain, fatigue, shortness of breath, and dizziness two days after receiving his first Pfizer vaccine in October 2021.

Within the week after taking the shot, Miller was found unconscious in his bathroom in Detroit.

“It’s been a scary experience,” he said, adding he still experiences similar symptoms and has been in and out of the hospital following his diagnosis.

Dr. Simone Gold,  founder of America’s Frontline Doctors, who was de-platformed by social media giants Facebook, Twitter, and YouTube for posting information surrounding COVID-19 in 2020, said Pfizer and Moderna are launching clinical trials to track vaccine-caused myocarditis in teens and young adults.

We were censored for exposing the dangers of these experimental biological agents,” Gold said. “Now, even the creators of the “vaccines” are forced to recognize the truth.”
