Protecting consumers from abusive financial practices and the burden of excessive regulation is a non-partisan issue, Elizabeth Warren, President Obama's special adviser for the new Consumer Financial Protection Bureau, told CNBC Wednesday.

Panel Chair Elizabeth Warren listens during a hearing before the Congressional Oversight Panel that was created to oversee the expenditure of the Troubled Asset Relief Program (TARP).

"I just can't believe there is someone who would want to come after this new agency," Warren said. "We're not a partisan agency—we're here for American families."
