The claim: Mayo Clinic staff member misdiagnosed pregnancies of Trump supporters

Recently, some social media users have been outraged to read a post in which a Twitter user purporting to be a doctor claims to be tricking supporters of former president Donald Trump into terminating healthy pregnancies.

"When Trump supporters come to my office at the Mayo Clinic, I love misdiagnosing their healthy pregnancies as ectopic so they have to abort their white fetuses," the tweet reads.

A screenshot of the tweet appeared in a June 14 Instagram post posted by conservative outreach group Young America's Foundation. The screenshot also included a tweet from another anonymous social media poster claiming to be a doctor who gives Trump supporters vitamins instead of antibiotics. More than 11,000 users liked the post in less than 24 hours, and other versions on Facebook and Twitter accumulated hundreds more interactions.

"Sickening," Young Americans captioned the image in their post. "What has the world come to when doctors are misdiagnosing patients intentionally because of their ideological views?"

But this is a hoax, and an old one at that.

The screenshot with the two tweets was posted in June 2018, according to WUSA 9 Verify and the Associated Press.  And there is no reason to believe the tweets are evidence of medical malpractice against Trump supporters, as other independent fact-checking outlets have also found.

The claim about the Mayo Clinic came from a parody account, web archives show. The social media poster also has no affiliation with the Mayo Clinic, according to a clinic spokesperson.

The second poster provided no evidence for the claims and appeared to be a parody as well.

USA TODAY reached out to social media posters who shared the screenshot for comment.
