We reported on Wednesday that 18 House Democrats are calling for a criminal investigation of Goldman Sachs. As of today, that number has more than doubled, reaching 44 lawmakers.

You can see the full list of signing members at the website of the Progressive Change Campaign Committee (PCCC), which is organizing a grassroots campaign to get more lawmaker support.

The SEC has of course filed a civil action against Goldman for allegedly selling investmant packages that were designed to fail. The SEC does not have authority to launch a criminal investigation, however, so the letter-signers are urging the Department of Justice to open their own probe.

The effort was spearheaded by Rep. Marcy Kaptur (D-Ohio).
