DiFi strikes back, sues bank and Kinde Durkee, alleges fraud

Emphasis added

Sen. Dianne Feinstein is suing her former treasurer and her campaign’s bank for fraud and breach of contract, alleging that the bank was complicit in a massive fraud case.

The complaint alleges that First California Bank was “at the heart of the illegal transfer out of plaintiffs’ accounts.” It quotes a letter from the bank to clients acknowledging that it appears Durkee had commingled funds and made transfers between accounts and that the balances credited to any given account may not accurately reflect the funds belonging to the associated campaigns.

While this is appalling and the FBI says Durkee has admitted guilt, I’m puzzled. Did the letter go political campaigns? If so, why didn’t they then immediately sever relations with Durkee & Associates?
