A top Senate Republican issued subpoenas for FBI informant and University of Cambridge professor Stefan Halper to provide documents and appear for testimony this month as part of a review of the Trump-Russia investigation.

Sen. Ron Johnson, chairman of the Senate Homeland Security and Governmental Affairs Committee, issued the subpoenas to Halper, 76, via the FBI informant’s lawyer Robert Luskin this week. They were exclusively obtained by the Washington Examiner.
