The US House of Representatives paved the way for criminal action against right-wing populist Steve Bannon for disregarding Congress.
The background is the reappraisal of the attack on the US Capitol on January 6th.
The Chamber of Parliament voted on Thursday to refer the case to the prosecutor.
229 MPs voted for it, 202 against.
Hardly any Republican joined the Democrats of US President Joe Biden and voted for it.
The committee of inquiry to investigate the attack had already unanimously adopted a report on Tuesday that found Bannon's disregard for Congress.
This cleared the first hurdle to bring Bannon to justice.
Now the Justice Department has to deal with the case.
On January 6, supporters of former President Donald Trump stormed the seat of the US Congress in Washington.
Five people were killed, including a police officer.
Bannon is suspected of having prior knowledge of plans for violent protests.
On Thursday last week, he disregarded a summons before the committee that dealt with the attack.
"He knew what was going to happen before it happened," Republican MP Liz Cheney said before the vote.
She is one of two Republican members on the committee.
“He's a bogeyman for the Democratic Party,” complained Republican Jim Banks, who is considered an ardent Trump supporter.
