An alt-right leader boasted about his links to the Trump administration to an anti-racism activist who spent a year undercover exposing the growing networks of influence of far-right groups in Britain and the U.S.

Swedish activist Patrick Hermansson infiltrated alt-right groups in Europe and the U.S. for the U.K.-based Hope not Hate anti-racism charity.  Earlier in the year, he claims he met with alt-right Iranian-American academic Jason Reza Jorjani in a New York.
