CREW released this statement after we got the news that the FEC Commissioners deadlocked 

Today’s decision indicates the FEC has finally recognized that at least in some cases, members of Congress should not be allowed to use campaign funds to bail them out of legal problems of their own making. This breaks with the FEC’s pattern of granting members permission to pay lawyers with campaign funds nearly every time the issue has been raised. It remains to be seen whether this is a one-time decision or whether the FEC really is breaking with its past precedents.

Here's how the Times-Picayune described the FEC proceedings:

Dividing along partisan lines, the Federal Election Commission couldn't agree Thursday on whether Sen. David Vitter, R-La., can use campaign money to pay all the legal costs related to his involvement in a Washington escort service scandal.

In a 3-3 vote, with all three Republicans voting yes and all three Democrats no, the commission deadlocked on whether Vitter could use campaign money to pay more than $160,000 in legal fees accrued in monitoring the federal criminal case against Deborah Jeane Palfrey, the so-called "D.C. Madam," and quashing her defense team's subpoenas of the senator. A majority vote is required for passage of a resolution.
