A new television advertisement by the conservative U.S. Chamber of Commerce goes after Miami Democratic Congressman Joe Garcia for backing the Affordable Care Act.
"Despite promises, premiums are still going up," the ad says, calling Obamacare "a big-government disaster that Congressman Joe Garcia still supports today."
The chamber has endorsed Garcia's Republican opponent, Miami-Dade County school board member Carlos Curbelo.
UPDATE: Garcia spokesman Miguel Salazar called the ad misleading and noted the Chamber once backed the former Republican incumbent.
"The truth is that Rep. Garcia has voted multiple times to improve the Affordable Care Act and has worked with Republicans to protect the Medicare that seniors have earned," Salazar said in a statement. "This group backed David Rivera before, and now they're behind Curbelo -- which should tell South Floridians all they need to know."
