Americans for Prosperity, the advocacy group funded by the wealthy Koch brothers, is launching a new round of anti-Obamacare ads against vulnerable Democrats.
Landrieu and Hagan voted to pass the health care law in 2010 and have since resisted GOP-led efforts to weaken the law. Both face competitive reelection fights in 2014.
"Lawmakers who have actively worked to bring about the disastrous Obamacare law need to be held accountable," AFP President Tim Phillips said in a statement. "Senators Hagan and Landrieu have steadfastly supported this costly, Big Government nightmare that has reduced choice, raised premiums, and led to the cancellation of health care plans for millions of Americans."
AFP said the latest ads are part of a "multimillion-dollar effort" that includes TV and Web ads against vulnerable Democrats who supported the Affordable Care Act.
