The day former Perkins Coie partner Michael Sussmann met with the FBI’s top lawyer in 2016 to share explosive allegations involving then-presidential candidate Donald Trump and Russia, he billed work on a “confidential project” to the Clinton campaign.

Sussmann billed about three hours that day, Sept. 19, 2016, to “work and communications regarding confidential project.” Prosecutors working for Special Counsel John Durham have used that billing record, which they showed the jury on Wednesday as they wrapped up their case, in an attempt to directly tie Sussmann’s meeting with the FBI’s then-general counsel, James Baker, to the Clinton campaign.
