Campaign Fundraisers and Votes: Purely coincidental

From the Washington Post:

The Office of Congressional Ethics is investigating eight lawmakers who held fundraisers within 48 hours of a major House vote on a Wall Street reform bill or received substantial donations from business people with a financial stake in the bill, according to congressional sources and letters.

The probe is focused on whether the timing of accepting the campaign checks created an unacceptable appearance of a conflict, according to sources familiar with the investigation and letters sent by the OCE to lobbyists requesting information.
