Andy Parrish, former chief-of-staff to Rep. Michele Bachmann's (R-MN), is expected to break his silence on allegations made by another aide that her 2012 presidential campaign violated Iowa Senate rules in making improper payments to its state chairman. The Star Tribune reports:

Until now, Parrish has been identified by the committee only as “Witness A,” Gilmore said.

“The time has come to confirm that ‘Witness A’ is Andy Parrish, and he’ll be providing an affidavit with supporting material that completely supports the representations previously made by Peter Waldron,” Gilmore said.
