The top Republican on the House Intelligence Committee signaled his desire to interview mysterious Trump-Russia figure Sergei Millian, allegedly an unwitting source for British ex-spy Christopher Steele’s dossier, after details emerged about the Russia investigation.

Rep. Devin Nunes of California said his own investigation of the Crossfire Hurricane investigators has zeroed in on three Russian Americans, telling Maria Bartiromo on Fox News’s Sunday Morning Futures he believed the most important was Millian, following recent revelations from Justice Department Inspector General Michael Horowitz’s report on the FBI’s Russia investigation.
