In news from Capitol Hill, two senior Democratic senators are coming under criticism for accepting special low-interest mortgages from Countrywide Financial, the mortgage firm at the center of the sub-prime lending crisis. The D.C. watchdog group Citizens for Ethics and Responsibility in Washington has filed an ethics complaint against the two Democrats, Chris Dodd of Connecticut and Kent Conrad of North Dakota. The publication Portfolio reported Dodd and his wife saved more than $70,000 because of the special treatment.
