Rep. Mario Díaz-Balart asserted Tuesday that Russia might already have nuclear missiles stationed in Venezuela as that country’s political turmoil continues to churn in the wake of a disputed presidential election.

Díaz-Balart, a longtime Florida Republican, provided no evidence to support his claim.

In a Tuesday segment on Fox News, host Tucker Carlson pressed Díaz-Balart on whether he thought the Chinese, Russian and Iranian military personnel presence in South America meant those countries might eventually invade the U.S.

Díaz-Balart demurred but invoked the Cuban Missile Crisis in 1962 where U.S. President John F. Kennedy and Soviet Union leader Nikita Khrushchev pushed each other to the brink of a nuclear war.

“The United States, the closest we ever came to nuclear war was because the Russians put missiles — right — nuclear missiles in Cuba,” Díaz-Balart said.
