Former White House chief strategist Stephen Bannon is expected to appear before the House Intelligence Committee on Tuesday as part of its investigation into Russian interference in the 2016 election.

Reuters reported Bannon’s expected appearance before the committee Thursday hours after reports surfaced that Bannon has hired Washington lawyer Bill Burck to help him prepare for his testimony.

Bannon's hiring of Burck is reportedly solely for the hearing and is not related to special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE’s investigation into potential ties between the Trump campaign and Russia.
