A political nonprofit aligned with House Speaker Paul Ryan on Wednesday launched a $2.5 million advertising campaign to urge Republicans to support tax reform legislation.

American Action Network is running television ads in 24 House districts encouraging Republicans to support an overhaul of the federal tax code, a politically complicated effort that has broken down each time it's been tried over the past few decades. Tax reform was last accomplished in 1986.

"It's time for Congress to act and defend hard-working Americans and their families across the country," AAN executive director Corry Bliss said in a statement.

The House and Senate are in the early stages of writing a tax reform bill with President Trump. Republicans are hoping the effort ends better than their failed, months-long effort to partially repeal Obamacare.

The ad from AAN is presenting the budding legislation as key to getting working class Americans who lost their jobs to foreign competition back to work.

"I was proud of my job. I was middle class, And it meant a better life for my daughter. But with more foreign competition – I got laid off," Albert Jones, described as a former metal worker, says as the ad opens. "America's tax code is so complicated – we can't be as competitive. Thousands of jobs like mine are lost to places like China. So when I see Congress working to cut taxes for working families, and brings jobs back. I know how that matters. Congress, pass tax reform that brings the middle class back."

The spot is running in districts held by these House Republicans:

  • Martha McSally of Arizona
  • Jeff Denham, David Valadao, and Steve Knight of California
  • Mike Coffman of Colorado
  • Brian Mast and Carlos Curbelo of Florida
  • Rod Blum of Iowa
  • Mike Bost of Illinois
  • Kevin Yoder of Kansas
  • Mike Bishop of Michigan
  • Bruce Poliquin of Maine
  • Erik Paulsen Minnesota
  • Don Bacon Nebraska
  • Tom MacArthur and Leonard Lance of New Jersey
  • Claudia Tenney and John Katko of New York
  • Pat Tiberi of Ohio
  • Ryan Costello and Brian Fitzpatrick of Pennsylvania
  • Kevin Brady of Texas
  • Barbara Comstock of Virginia

The ad also is running in Ryan's district in southeast Wisconsin. AAN has pledged to spend millions of dollars pushing tax reform over the next several months.
