He was called the “Walrus,” but Cambridge University professor Stefan Halper seemed remarkably agile and active in making contacts with Trump campaign officials in the summer and fall of 2016. Indeed, he not only actively consulted with at least three Trump campaign advisers but appears to have sought a position in the Trump administration.
Ordinarily that would not be notable. After all, Halper served in prior administrations, was a moderate Republican, and is a recognized academic who shared Donald Trump’s hardline view of China. The problem is that Halper also may have been a paid informant for the FBI and CIA. Halper’s role has triggered a justified referral by Deputy Attorney General Rod Rosenstein for investigation by the Justice Department inspector general. The allegations fall into a gray area of DOJ guidelines which limit “overt” acts before an election but are ambiguous on covert acts like running the Walrus.
