Capitalizing on populist anger toward Wall Street, a coalition of more than 20 labor unions and activist groups on Tuesday launched a new campaign to reform the financial industry.

The group, Take On Wall Street, plans to combine the efforts of some of the Democratic Party’s biggest traditional backers, from the American Federation of Teachers and the AFL-CIO to the Communications Workers of America. The group says it will aim to turn the public’s lingering anger at the financial sector into policy initiatives that could change the way that Wall Street works.
