Brian Jack, the White House's director of political affairs, was subpoenaed by the committee after he reached out to a member of Congress.
Ed Martin, a prominent conservative activist who is representing at least two of the defendants charged with breaching the Capitol, was one of the six subpoenas. Martin helped promote the events.
The depositions will take place between Jan. 4 and 10. It is an indication that the investigation will continue in the new year, even as the panel prepares for a series of public hearings to present its findings in the spring.
Bennie Thompson said the subpoenas were directed at individuals who were involved in or witnesses to the coordination and planning of the events leading up to the attack on our democracy.
There are a few complicated conflicts created by the subpoenas. Two of them are directed at Democrats. Miller is trying to succeed Anthony Gonzalez, who is retiring after facing backlash for voting to impeach Donald Trump.
The committee issued a public statement on them a day before Miller knew about the subpoena. Miller said he would accept service of the subpoena, but he would defend his rights just as he would defend his own. He promised to vote to end the panel if elected.
Jack works for the political arm of House GOP leader Kevin McCarthy, which is trying to wrest the majority from Democrats and, specifically, to defeat two members of the Jan. 6 committee.
In a public statement, he described his interaction with Jack and his defense of himself against claims that he helped cause the attack on the Capitol. In his statement, he described how he came to speak at the rally.
On Tuesday morning, January 5, I had a telephone call with Brian Jack, White House Political Director. He asked me to speak at the Trump rally the next day. I was invited to address Trump volunteers and supporters by the White House because I had never attended a Trump rally in my life but had seen many on TV, so I readily agreed.
A person familiar with the event told POLITICO that Jack, a congressional liaison for Trump, had been asked by organizers to pass along an invitation but otherwise had no role in organizing the event.
Martin is known for his work for the Eagle Forum, and he recently joined the defense team for the January 6 defendants.
Bryan Lewis was summonsed by the panel after applying for a permit to hold a demonstration about the electoral vote count.
The panel subpoenaed a conservative activist who helped organize two rallies. The panel said it had documents showing her correspondence with the Stop the Steal organizers.
