With its deep pockets, the U.S. Chamber of Commerce inserted itself into the suburban Miami congressional race where Republican U.S. Rep. Carlos Curbelo is seeking re-election, introducing two ads on immigration.

The TV ad goes into rotation as part of an existing media buy, which began with a digital ad last week. The chamber focuses on what it calls Curbelo‘s leadership for Dreamers under the Deferred Action for Childhood Arrivals policy, which the Trump administration wants to phase out.
