Rep. Elijah Cummings, ranking member of the House Oversight and Government Reform committee, sent a letter on Tuesday to the panel’s chairman, Darrell Issa, pressing the leader to subpoena six mortgage servicing companies. This is Cummings’s fourth letter to Issa urging the committee to take action on the foreclosure crisis. In it he notes particular alarm over increasing reports of U.S. service members and their families being illegally evicted from their homes and charged millions of dollars in unwarranted fees.

In February, Cummings and other Democratic committee members sent letters to ten mortgage companies, but only four responded with the requested documents. One company, MetLife, refused to voluntarily release any documentation and said it would only do so if ordered by a subpoena.

Particularly in light of the Committee’s unanimous vote in February of this year to investigate “wrongful foreclosures and other abuses by mortgage servicing companies,” it would be behoove Chairman Issa to grant Cummings’s more than reasonable request.

In these difficult economic times, millions of Americans are paying more than they can afford at the gas pumps, worrying about job security, and losing their homes because of fraudulent and mismanaged foreclosures. It is imperative that Congress fight to hold big banks and mortgage companies accountable for their role in pushing the country into economic crisis.

Chairman Issa must do his part by supporting his Democratic colleagues in their fervent commitment to investigating and responding to mishandled and deceitful mortgage practices. Protecting American families from abuse and other corporate wrongdoings that put their finances in jeopardy is not an issue to be dealt with by playing partisan politics. Congress has a responsibility to stand up for the American people and do everything in its power to get to the bottom of and put an end to the foreclosure crisis.
