Rubio Testifies Against Friend in Corruption Case

Secretary of State Marco Rubio became the first U.S. cabinet member to testify in a criminal case in over four decades Tuesday, when he appeared in court in a corruption trial of his long-time friend David Rivera.

Rubio and Rivera were roommates in college and subsequent political allies. Rivera represented Florida's 25th district in Congress from 2002 to 2010.

He is charged with money laundering and failing to register as a foreign agent. The prosecution claims he took $50 million to lobby on behalf of the Venezuelan government to get the U.S. government to ease sanctions on the South American nation.

"He's someone I've known for a long time. We've worked closely together but not on this," Rubio said.
