With subpoena power, Democrats will likely return to other Trump advisers and associates who have refused to answer questions during committee appearances. I would anticipate the House Intelligence Committee will recall the following (non-exhaustive) list of witnesses:
• Steve Bannon, former chief Trump campaign strategist and White House adviser, for his refusal to testify about the presidential transition, his communications with Trump since leaving government, and his involvement with Cambridge Analytica.
• Hope Hicks, former White House communications director, for her refusal to testify about her White House tenure and the presidential transition.
• Corey Lewandowski, former Trump campaign manager, for his refusal to testify about his conversations with Trump about the June 2016 Trump Tower meeting, Trump’s firing of Comey, and Trump’s efforts to fire Mueller.
• Roger Stone, to address new information about his knowledge of WikiLeaks possession of stolen Democratic emails and his interactions with Randy Credico as a conduit. In consultation with the special counsel, the committee may also consider a grant of immunity to Credico, who has indicated an intent to assert his Fifth Amendment right against self-incrimination. And the committee may now grant the special counsel access to Stone’s committee interview transcript.
The committee will also likely seek to engage the special counsel to help arrange testimony by witnesses cooperating with law enforcement, including: Michael Cohen, Michael Flynn, Rick Gates, Paul Manafort, and George Papadopoulos.
