In a series of tweets and video statements, Rubio also suggested the FBI raid during Biden's presidency against a potential political opponent in 2024 is akin to what the world has seen "many times from 3rd world Marxist dictatorships" but never before in the U.S.
Rubio, whose parents are natives of Cuba, also warned the Biden administration and federal departments over the unprecedented escalation of a law enforcement inquiry into a former president.
"I'm telling you, you're playing with fire," Rubio said. "This is dangerous, because someone else will be in power one day, and now you have created the precedent for them to do this back to you.
"And then we become the Third World, and then we lose our country, and our system of government and the meaning of being one nation under a real constitution.
"This needs to stop and the people responsible for this decision, [Attorney General]
Merrick Garland, the director of the FBI [Christopher Wray], need
to be held to account for going along with something so undemocratic, unconstitutional, and flat out destructive and dangerous to our republic."
