May 1 (UPI) — Former U.S. Rep. David Rivera, R-Fla., was found guilty on Friday of being paid to secretly lobby elected U.S. officials to ease sanctions against Venezuela.

Rivera and a co-conspirator were each found guilty of taking payment from Nicholas Maduro to try to repair ties between the South American nation and the United States but never registering as an agent of a foreign country, The Miami Herald and NBC News reported.

A 12-person jury found the former Miami-Dade congressman and consultant Esther Nuhfer guilty of lobbying Secretary of State Marco Rubio and Rep. Pete Sessions, R-Texas, and attempting to set meetings up for Delcy Rodriguez, Venezuela’s then-foreign minister and current acting president.

Rivera was also found guilty of conspiring to commit money laundering and tax evasion.

Rivera had long been friends with his former roommate Rubio and became friends with Sessions when he was in Congress, and after Maduro gave him a $50 million contract he attempted to leverage those relationships.

Both Rivera and Nuhfer were caught having not registered themselves of lobbying for the federal government on behalf of another nation.

The convictions come after a 5-week trial that saw Rubio, who was in the Senate in 2017, when he met with Rivera and was told a plan to convince Maduro to step down was afoot.

Rivera denied that he was working on behalf of Maduro and the Venezuelan government, insisting that he was working to overthrow the now-deposed ruler rather than to promote his interests.

Nuhfur was released on bond ahead of her sentencing, while Rivera was judged to be a flight risk and will remain in jail until he is sentenced.

Rivera also still faces charges in another foreign lobbying case, as well.
