The Office of Special Counsel is a separate body from special counsel Robert Mueller’s investigation into possible collusion between the Trump campaign and Russia in the 2016 presidential election.
In a statement to CNN, Zinke said the probe’s conclusion was “no surprise.”
“Every false allegation and subsequent investigation has resulted in the same conclusion: I followed all rules, regulations, and most importantly the law,” the former Trump administration official said, adding that unfounded allegations have the potential of “destroying the reputation of those who are willing to serve our great nation.”
