Details on Marco Rubio's testimony in former roommate's illegal lobbying trial

Secretary of State Marco Rubio testified Tuesday in the federal case against former Rep. David Rivera, his ex-roommate, who faces charges of illegally lobbying on behalf of Venezuela. Rivera has denied the allegations against him. Rubio's appearance as a witness underscores the intersection of his past personal relationship with Rivera and his current role as the nation's top diplomat, a position that makes him a central figure in U.S. foreign policy toward Venezuela. The case centers on whether Rivera improperly represented Venezuelan interests without registering as a foreign agent, a violation of federal law. Rubio's testimony could provide insight into Rivera's activities and their relationship during the period in question.
