The invitation, which did not come in the form of a subpoena forcing them to testify, was for a “voluntary interview” in the committee’s offices, which means it would be held behind closed doors, the official said.
Along with Bannon, former Trump campaign manager Corey Lewandowski also received a letter of invitation. Though the letter made no mention of why the two were invited to testify, it did indicate the interviews are directly related to the ongoing Russia probe.
Bannon, who worked as Trump’s top strategist during the campaign and for several months in the White House, has not been publicly accused of any wrongdoing.
Before Lewandowski left, he was among several senior Trump campaign officials who received communications from foreign policy adviser George Papadopoulos about his outreach to the Russian government, according to published news accounts.
