Secretary of State Marco Rubio took the witness stand in Miami federal court, testifying against his former political ally David Rivera in a corruption trial involving alleged secret lobbying for Venezuela's government. The high-profile testimony drew significant attention as Rubio, once a close friend of Rivera, spent hours detailing their relationship and political dealings.

Rivera, a former U.S. congressman from Florida, faces charges of acting as an unregistered foreign agent. Prosecutors allege he worked behind the scenes to advance Venezuelan government interests while concealing his activities from U.S. authorities. The case has exposed the complex web of political connections between Florida politicians and foreign governments.

The trial represents a dramatic fall from grace for Rivera, who once served alongside Rubio in Florida's legislature before both rose to national prominence. Their relationship has become a focal point of the proceedings, with Rubio's testimony potentially proving pivotal to the prosecution's case.
