AFL-CIO plugs Warren for consumer protection chief

"We therefore strongly urge President Obama to appoint Professor Warren as Director of the new consumer protection bureau. Professor Warren's appointment would make clear that under President Obama's leadership, there truly will be accountability for Wall Street and fair treatment for the American public in the financial marketplace," the AFL-CIO statement says.

Warren also is chairwoman of the Congressional Oversight Panel, which scrutinized the government's handling of the Troubled Asset Relief Program. She was not afraid to throw a few elbows as a tough leader of the panel and she often upset Republicans and financial sector executives.

That won her fans though among liberal activists and labor unions, with some putting her on the short list for a Supreme Court nomination from President Obama.
