Ex-senior Trump adviser Stephen Miller testifies to Jan. 6 federal jury: report

Miller could be the first known witness to be interviewed since a special counsel started overseeing the probe.

Former senior Trump adviser Stephen Miller reportedly met with a Washington, D.C., federal grand jury investigating the Jan. 6, 2021, Capitol riot.

Miller spent several hours at the downtown federal courthouse Tuesday, a person familiar with the probe told CNN. Top Jan. 6 prosecutor Thomas Windom was also seen at the courthouse that day.

Miller could be the first known witness to be interviewed since a special counsel started overseeing the probe. He would be able to offer first hand testimony about former President Donald Trump's activities leading up to Jan. 6. 

The Justice Department subpoenaed Miller for the federal probe in September. He testified about Jan. 6 for the first time during an eight-hour interview in April with the House committee investigating the riot. That interview was completely separate from the federal grand jury testimony.
