Two top former Trump advisers were subpoenaed this week as part of the Justice Department’s wide-ranging investigation into the events surrounding the Jan. 6 Capitol riot and its aftermath, according to the New York Times. Stephen Miller, a senior Trump White House policy adviser, and Brian Jack, Trump’s political director, were among a dozen people in the former president’s inner circle subpoenaed by a federal grand jury this week, the Times reported. Miller and Jack did not immediately respond to a request for comment. The calls appear to seek information about Trump’s main fundraising operation, Save America, which was formed after the 2020 election, and the alleged plot to rig the 2020 vote by sending a slate of fake voters to disputed states, according to with the Times. On Thursday, the Times also reported that the Justice Department is looking into the PAC based on about half a dozen subpoenas to former lower-level Trump aides, including Nicholas Luna and Ivanka Trump’s chief of staff, Julie Radford. It remains unclear why exactly the PAC is being investigated and how it might be related to the Capitol uprising The subpoenas for Miller and Jack are also related to Trump’s PAC as well as the 2020 voter plan, according to the Times. In addition to the ongoing investigation into Trump’s handling of official government records, the Justice Department is investigating the Capitol hack, any obstruction of that investigation, and the voter fraud conspiracy. Miller was subpoenaed by a House select committee investigating Jan. 6 about his phone records earlier this year. The adviser filed a lawsuit to block the subpoena, CNN reported. He previously sat for a deposition with the panel. Jack, who still advises Trump, was also subpoenaed by the committee last year. So far, at least 40 members of Trump’s inner circle are publicly known to have cooperated with federal and congressional investigators.
