Trump aide Stephen Miller will appear before the congressional committee investigating the Jan. 6 insurrection. That's according to two people familiar with the matter.

It’s unclear whether Miller will appear Thursday in person or virtually. Miller hasn’t returned a message seeking comment.

Miller was a senior adviser for policy during President Donald Trump's administration and a central figure in many of the Republican's policy decisions. Miller had resisted previous efforts by the committee, filing a lawsuit last month seeking to quash a committee subpoena for his phone records.

The people familiar with the matter spoke on the condition of anonymity to discuss private testimony.

The committee has sought testimony from a number of members of the Trump administration. A week ago, the House voted to hold advisers Peter Navarro and Dan Scavino in contempt of Congress. The matter was referred to the Department of Justice for possible prosecution.
