In a real social media post, did Donald Trump write about a Joe Biden visit to Moscow in 1987 and implicate him in various conspiracy theories? No, that's not true: The supposed post does not appear on the president's official Truth Social account, and there are no reliable reports that it ever did. Biden also never visited Moscow in 1987.
The claim appeared in a post and image (archived here) by the @glenn_tunes account on X on May 17, 2026. It read:
25TH AMENDMENT NOW ✊✊✊
This is what the post looked like on X at the time of writing:

The text included in the fake screenshot read:
SLEEPY JOE was a RUSSIAN AGENT!
He was invited to MOSCOW in 1987 and that's when he became compromised!
That's why RUSSIA helped him STEAL the 2020 election from ME! They even used CHINA to spread THE FAKE COVID VIRUS using 5G towers and inside WAYFAIR FURNITURE! The "Joe Biden" that sometimes did press conferences was actually BARACK HUSSEIN OBAMA in a VERY WELL made HOLLYWOOD MASK!!
Everyone now knows that. THANK YOU FOR YOUR ATTENTION TO THIS MATTER.
Lead Stories manually reviewed Trump's Truth Social account for recent posts containing the phrase "SLEEPY JOE was a RUSSIAN AGENT!" Lead Stories also searched Trump's Truth -- a website that archives Trump's Truth Social posts -- for the same phrase. No matching posts were found (archived here).
Lead Stories searched Google News (archived here) and Yahoo! News (archived here) and did not find any matching reports for "Joe Biden was a Russian agent." Had the president actually made such a post, major news outlets would have widely reported it.
The fake post also suggested Biden was invited to Moscow in 1987 and "became compromised." Biden visited Russia several times during his political career (archived here) as a senator, vice president and president, but not in 1987.
