Sounding another alarm for progressives wary of the Democratic establishment’s support for Wall Street, Virginia Sen. Tim Kaine—has just this week sent a clear message to big banks: He’s in their corner.

Kaine signed onto two letters on Monday pushing for financial deregulation—letters that show the Clinton camp “how Kaine could be an asset with banking interests on the fundraising trail,” according to David Dayen at The Intercept on Wednesday.

The news should “disqualify” Kaine from the ticket, one prominent progressive group declared Thursday.
