Rivera suspended his congressional bid in July.
“What was announced [in July] was the suspension of campaign activities,” Rivera told the Miami Herald.
“Meanwhile, the state legislature dealt with the reconfiguration of electoral districts,” he added.
The Florida legislature approved new congressional district maps on Monday, following a judge's ruling that the prior maps illegally gave Republicans running for the U.S. House an unfair advantage and would need to be redrawn.
That court ruling prompted Rivera to suspend his campaign. "As a congressional candidate affected by this decision, I will not be held hostage by Florida’s liberal activist judges," Rivera said in a statement in July.
Rivera faces four GOP primary candidates in his bid to unseat Rep. Joe Garcia (D-Fla.).
