Senator Warren reams banking committee 'expert'

So the Republican-controlled Senate banking committee holds a hearing to evaluate the effects of consumer financial regulation. One of their assumptions is that is just costs too damned much to enforce such regulations. Warren then turns the tables on the costs of not doing so which led to the financial crisis. The Republicans choose as their expert on this the guy who claims there was no data to even see the crisis coming when it was obvious to so many. Another fine example of the difference between those controlled by Wall Street and those like Warren and Sanders that are representative of the people.
