U.S. Justice Department officials are connected to mortgage banks.

The firm, Covington & Burling, is one of Washington's biggest white shoe law firms. Law professors and other federal ethics experts said that federal conflict of interest rules required Holder and Breuer to recuse themselves from any Justice Department decisions relating to law firm clients they personally had done work for.

Both the Justice Department and Covington declined to say if either official had personally worked on matters for the big mortgage industry clients. Justice Department spokeswoman Tracy Schmaler said Holder and Breuer had complied fully with conflict of interest regulations, but she declined to say if they had recused themselves from any matters related to the former clients.

Reuters reported in December that under Holder and Breuer, the Justice Department hasn't brought any criminal cases against big banks or other companies involved in mortgage servicing, even though copious evidence has surfaced of apparent criminal violations in foreclosure cases.

Court records show that Covington, in the late 1990s, provided legal opinion letters needed to create MERS on behalf of Fannie Mae, Freddie Mac, Bank of America, JP Morgan Chase and several other large banks. It was meant to speed up registration and transfers of mortgages. By 2010, MERS claimed to own about half of all mortgages in the U.S. -- roughly 60 million loans.

But evidence in numerous state and federal court cases around the country has shown that MERS authorized thousands of bank employees to sign their names as MERS officials. The banks allegedly drew up fake mortgage assignments, making it appear falsely that they had standing to file foreclosures, and then had their own employees sign the documents as MERS "vice presidents" or "assistant secretaries."
