The defense secretary was appointed by the president after he lost the election to investigate a voter fraud conspiracy.

After losing the election to Joe Biden, Trump fired Defense Secretary Mark Esper and replaced him with Christopher Miller. Miller was the director of the National Counter terrorism Center.

According to testimony from the January 6 committee hearing, Miller had an election conspiracy theory that claimed that an Italian defense contractor uploaded software to a satellite that would switch votes between Trump and Biden.

The baseless theory made its way to the White House after a congressman sent a video to the chief of staff.

Richard Donoghue, the acting US deputy attorney general, was the one who received the video. Donoghue said he watched the video at the time.

The email I sent the acting attorney general was "pure insanity", Donoghue said.

Miller looked into the theory after it was brought to the attention of the Department of Defense.

Miller contacted the defense attache in Italy to inquire about the claim.

Can you call the defense attache in Rome to find out what's happening? Miller said that the guy on the ground probably knows more than he does.

This is one of the best examples of the lengths to which President Trump would go to stay in power, according to Kinzinger.

When Trump left office, Miller was the acting Defense Secretary. He told reporters that he couldn't wait to leave.

According to Jonathan Karl's book "Betrayal," he acted like a "fucked madman" to discourage Trump from attacking Iran.
