The Justice Department is asking for the so-called QAnon Shaman, who wore a headdress and posed shirtless on the Senate floor during the siege of the US Capitol, to be sentenced to a prison term of more than four years, the longest incarceration prosecutors have asked for any guilty January 6 defendant so far, according to a new court filing.

Prosecutors' request for the high-profile Capitol riot defendant Jacob Chansley is as a harsh assessment of his crime and calls him "quite literally, their flagbearer" among the mob on January 6.

In their sentencing request to the judge filed late Tuesday night, prosecutors made clear they hope to use Chansley's sentence as an example to deter future attacks on the government.

The attempted coup, prosecutors wrote, "has made us all question the safety and security of the country in which we live."

"Those enormous harms, borne out of the acts of this defendant, must be deterred so that we never see a similar assault on our democracy again," they continued.

Chansley is set to be sentenced next Wednesday by Federal Judge Royce Lamberth of the DC District Court, as one of the first felony defendants to receive his punishment. He has been in jail for nearly 10 months....
