WASHINGTON >> An Iowa construction worker and QAnon follower was sentenced Friday to five years in prison for his role in the Jan. 6, 2021, insurrection at the U.S. Capitol, when he led a crowd chasing a police officer who diverted rioters away from lawmakers.

Wearing a T-shirt celebrating the conspiracy theory with his arms spread, Douglas Jensen became part of one of the most memorable images from the riot.

As he handed down the sentence, Judge Timothy Kelly said he wasn’t sure Jensen understood the seriousness of a violent attack in which he played a “big role.”

“It snapped our previously unbroken tradition of peaceful transfer of power. We can’t get that back,” Kelly said. “I wish I could say I had evidence you understood this cannot be repeated.”

Jensen was convicted at trial of seven counts, including felony charges that he obstructed Congress from certifying the Electoral College vote and that he assaulted or interfered with police officers during the siege. His sentence also includes three years of supervised release and a $2,000 fine.

He gave a brief statement to the judge, saying that he wanted to return to “being a family man and my normal life before I got involved with politics.”

Jensen scaled a retaining wall and entered through a broken window so he could be one of the first people to storm the Capitol that day, Kelly said. He led a group that chased Capitol Police Officer Eugene Goodman up a staircase. He would later re-enter the building and scuffle with police.

“Doug Jensen wanted to be the poster boy of the insurrection,” prosecutor Emily Allen said.

Jensen wore a T-shirt with a large “Q” on it because he wanted the conspiracy theory to get credit for what happened that day, his defense attorney Christopher Davis said.

Approximately 900 people have been charged with federal crimes for their conduct on Jan. 6. More than 400 of them have pleaded guilty, mostly to misdemeanor offenses.
