Christopher C. Miller

Christopher Charles Miller (born October 15, 1965) is an American retired United States Army Special Forces colonel who served as acting United States secretary of defense from November 9, 2020, to January 20, 2021. He previously served as Director of the National Counterterrorism Center from August 10 to November 9, 2020. Before his civilian service in the Department of Defense, Miller was a Green Beret, commanding 5th Special Forces Group in Iraq and Afghanistan, and later spent time as a defense contractor.

Miller's tenure in the Trump administration began as Director of the National Counterterrorism Center, confirmed by voice vote in the United States Senate on August 6, 2020. President Donald Trump named Miller acting defense secretary after firing Mark Esper on November 9, 2020, six days after the 2020 presidential election. Miller was accused of obstructing the transition to Joe Biden's administration by Biden staff, which Miller denied.

Miller was criticized for his response to the 2021 storming of the United States Capitol. He approved the deployment of National Guard troops from neighboring states to reinforce the D.C. National Guard at 4:41 p.m., three hours after Capitol Police said that they were being overrun and two hours after city officials had asked for such assistance. Miller later testified that he had no need to speak with the President on January 6 because, "I had all the authority I needed and I knew what had to happen", and he said the delay was because he wanted to avoid a repeat of the Kent State shootings.

Upon the inauguration of Joe Biden on January 20, 2021, Miller was succeeded by then-Deputy Secretary of Defense David Norquist.
