Elizabeth Warren frequently does.  From the story:

Elizabeth Warren, assistant to the President and special advisor to the Secretary of the Treasury on the Consumer Financial Protection Bureau, kicked off a conference for the anniversary of the Credit Card Accountability, Responsibility and Disclosure Act, more commonly known as the Credit CARD Act, by praising the credit card industry for going beyond the requirements of the law to ensure clarity and transparency for consumers.

“A year later, the CARD act has brought about major changes in the way the industry operates,” Warren said in the keynote address.  “Much of the industry has gone further than the law requires in curbing repricing and over limit fees.  A number of issuers have eliminated some of the practices that can confuse customers and cost them money they reasonably did not expect to pay.  Lenders in the industry deserve credit for moving in the right direction.”
