Tucker Carlson has gone after Republican Members of Congress who are supporting a 9/11-style commission into the January 6 attack on the US Capital.

Speaking on his Fox News show Tuesday night, Carlson said the commission would become a partisan witch hunt and 'give power to Nancy Pelosi'.

'It's a complete farce. It's partisan as hell... Don't play along with the fraud,' he said.

'We don't need a 9-11 style commission to see it and they could tell us who shot Ashli Babbitt, the only person killed that day.'

Carlson called out John Katko, the New York Republican appointed to negotiate the terms of the commission with Democrats.

'Republican voters deserve to know the name of every congressional Republican that votes for this farce,' said Carlson.

'They should know which representative is playing along with this poisonous hoax.'

Earlier on Tuesday, House Republican Minority Leader Kevin McCarthy and Whip Steve Scalise encouraged members of the party to vote against the creation of a commission to investigate the January 6 MAGA riot.

Speaking on his primetime Fox News show Tuesday, Carlson said Republicans who support the Commission were playing into Democrats' hands.

'House Speaker Nancy Pelosi said this commission is about finding the truth, but she is the same person who supported BLM and the Antifa riots over the summer.

'In a civilized country you punish people equally for the same crimes.

'That's the opposite of what we're seeing now.'

Carlson said when the Trump administration sent Federal agents to stop Antifa, Pelosi claimed it was a violation of their dignity and human rights.

'Why? Cause they're her voters and she defends them at all cost.

'They are voting to give Nancy Pelosi and Chuck Schumer and Joe Biden more power, power they do not deserve.'

Senate Minority Leader Mitch McConnell also reportedly told a closed-door meeting of Republicans Tuesday that he couldn't support the commission, Axios reported.

McConnell had earlier said he was 'pressing pause' on legislation for the commission, adding the GOP conference is 'undecided.'

Steve Scalise, the No. 2 Republican in the House, sent out a note Tuesday afternoon in advance of a planned Wednesday vote, saying: 'Leadership recommends a NO vote.'

McCarthy, the top Republican, came out against the legislation saying he was against it because it didn't look at 'interrelated forms of political violence' such as Antifa and Black Lives Matter.

He did so amid speculation that his own angry phone call with former President Donald Trump on Jan. 6th could feature in the commission's line of inquiry.

The move comes days after Trump loyalist Rep. Elise Stefanik, a New York Republican, replaced critic Liz Cheney of Wyoming in GOP leadership.

McCarthy said he wanted the new panel to look beyond the violent uprising by supporters loyal to Donald Trump, who were trying to stop the certification of President Joe Biden's election.

He pushed to have the new commission also investigate other groups, namely the Black Lives Matter groups that protested police violence in the aftermath of the death of George Floyd.

But House Speaker Nancy Pelosi and the top Republican on the House Homeland Security Committee who drafted the proposal rejected that approach.

Pelosi ripped McCarthy when asked about his latest posture.

'I'm very pleased that we have a bipartisan bill to come to the floor, and it's disappointing but not surprising that the cowardice on the part of some on the Republican side not to want to find the truth,' she told reporters in the Capitol.

Asked if she anticipated getting GOP support for the commission – which has gotten unequivocal backing from Cheney – Pelosi responded: ''We'll see.'

McCarthy said that given the 'shortsighted scope that does not examine interrelated forms of political violence in America, I cannot support this legislation.'

Scalise's memo to Republicans said the commission wouldn't be able to investigate 'the political violence leading up to and following the attack on the 6th, including the June 2017 shooting at the Republican Congressional baseball practice, and the deadly attack on Capitol Police on April 2, 2021.

Scalise was wounded during the Congressional baseball practice attack.

The shooter, who died from wounds suffered in the attack, was a supporter of Bernie Sanders' 2016 presidential run.

The more recent Capitol car attack was carried out by a man who was a follower of the Nation of Islam.

With House GOP leadership firmly against the bill, it all but ensure this week's vote will have less support in the House, and dims its chances in the evenly divided Senate.

McCarthy and Scalise's stance came despite their own appointed negotiator John Katko reaching an agreement with Democratic Rep. Bennie Thompson of Mississippi on the commission.

'While Ranking Member Katko negotiated in earnest to improve upon previous proposals, Speaker Pelosi delayed for months and prevented the inclusion of a wider investigatory scope, proving her main concern is politics over solutions,' Scalise wrote in his memo.

Language to create the commission gives subpoena power – and either the majority or minority could exercise it.

McCarthy's comments come after Senate Minority Whip John Thune of South Dakota predicted the commission would pass the Senate 'in some form,' and predicted it would pass the House by a wide margin.

Thune called for it to be 'principally focused on what happened on the sixth' – the day of the riot.

But in the latest sign of Republican lawmakers struggling to position themselves around Trump, Sen. John Cornyn said Monday: 'I don't know why you would tie their hands if they want to pursue some other connection,' CNN reported.

'I mean, I'd be surprised if anything they find out about January 6th fully developed on that day. So I would not tie their hands.'

'Why can't they just follow the evidence where it leads?' he added.

One added hang-up for McCarthy: he may be required to testify to the commission owing to his Jan. 6th phone call with Trump where he reportedly yelled for the president to send the MAGA mob home.

There were multiple reports in the aftermath of the riot on an angry phone call between McCarthy and Trump, with McCarthy telling Trump: 'Who the f--k do you think you are talking to?'

Lawmakers say Trump told McCarthy: 'Well, Kevin, I guess these people are more upset about the election than you are.'

Trump repeatedly referred to McCarthy, who aims to be speaker if Republicans take over the House, as 'My Kevin.'

The two met at Mar-a-Lago after Trump left the White House to discuss strategy.

Pelosi came out initially for a panel where Democrats would hold ultimate control, but the final deal is split evenly, with McCarthy and other leaders all getting an even hand in appointing commissioners.
