Jurors found Rivera and an associate guilty on all counts, including failing to register as a foreign agent with the U.S.

Justice Department and conspiracy to commit money laundering.

The charges stemmed from his undisclosed work for former Venezuelan dictator Nicolás Maduro's government.

Rivera, a Republican, represented Florida's 25th district from 2011 to 2013.

Federal prosecutors had argued Rivera was recruited by the regime to lobby Congress and the White House to ease sanctions on Venezuela.

Attorneys for Rivera say the ex-Congressman acted in good faith and was unaware he had to formally register as a foreign agent.

The date for Rivera's sentencing hearing has not been announced.

He faces additional federal charges in a related foreign lobbying case in Washington, D.C.
