Rivera, who’s charged with acting as an unregistered foreign agent for Venezuela President Nicolás Maduro’s government, has a decades-long personal and political relationship with Rubio. The two men have known one another for decades, and even owned a home together in Tallahassee at one point. They served alongside one another in the Florida state House and Rivera won his U.S. House seat the same year Rubio was elected to the Senate.

But their paths have diverged wildly since then. Rivera lost reelection after a single term in Congress and went on to face a litany of legal troubles. Rubio, now in his third term in the U.S. Senate, is a top contender to serve as former President Donald Trump’s running mate.
