The acquittal this week of former Perkins Coie partner Michael Sussmann on a false statements charge has revived criticism of Special Counsel John Durham’s investigation and resurfaced claims of improper political influence that dogged the Trump-era Justice Department.

Sussmann, a cybersecurity attorney who represented Hillary Clinton’s 2016 campaign, was accused of lying about his client representations in a 2016 meeting with the FBI, during which he shared allegations about purported ties between then-candidate Donald Trump and Russia. Durham’s prosecutors alleged that Sussmann’s false statement was part of an effort by people connected to Clinton to elicit an FBI investigation into Trump to wound his candidacy in the waning weeks of the campaign.
