The representative Republican from Indiana Jim Banks was about to send a letter to Democrats asking for a GOP witness for the first select committee hearing on January 6 when he had the carpet removed from under him . Speaker Nancy Pelosi announced Wednesday afternoon that she refused both Banks and Rep. Jim Jordan , a Republican from Ohio, to participate in the investigation because of their role in overturning the presidential election results - an unprecedented move that injected fresh fuel into the partisan brawl.The five members of the GOP which Kevin McCarthy, leader of the parliamentary minority, leaned on for ' sit on the panel had already prepared their counterattack , with Banks, the new ranking member, planning to call the Union Police chief from the Capitol - who criticized security loopholes this day - to testify, sources tell CNN. The banks even had a phone call early Tuesday night with the select President Democrat on the committee, Rep. Bennie Thompson of Mississippi, to begin laying the groundwork for how the two sides would navigate what was shaping up to be a protracted investigation. Banks asked if the GOP would be able to do so. 'call their own witnesses, if they could have more time tothe first audience and what kind of resources they would have for staff. There was no indication at that time that we would not be working not together, Banks told CNN of his phone call with Thompson, which took place less than 24 hours before Pelosi's decision. Read more But what became obvious to me was is that, because we immediately started asking about vulnerabilities in the Capitol on January 6, they weren't comfortable with it ... They got scared. While many Republicans were caught off guard by Pelosi 's astonishing move, which prompted McCarthy to remove all of his committee members, the GOP ultimately believes this result to be a political giveaway to them, with some sources describing it as a big mistake for Democrats. Now they feel like they have even more ammo to back up their claimsthat Pelosi is only playing politics with the investigation and presenting Pelosi's veto as an example of Democratic overtaking. Nancy Pelosi has just condemned the already tiny chances that the 1/6 committee really counts And while some Republicans thought it was important tosee GOP representation on the panel so they can play the defense and shape the counter-narrative, others never wanted their party to sit on the committee anyway, knowing they should facing uncomfortable questions about former President Donald Trump and his role in inciting violence that day. McCarthy now promises to continue her own focused investigation into the Capitol building security failures on Jan. 6. Nancy Pelosi is a radical authoritarian Speaker of the House, said House GOP Conference chairperson Elise Stefanik of New York. The American people have always known the truth - that the Pelosi Party Commission of January 6 was never intended to investigate the facts, it was only the radical policies of Pelosi and the The left's endless obsession with crushing any discussion or debate. Democrats, however, vehemently rejected the idea that Bank's rejections and Jordan would fuel the GOP narrative that the committee is just a partisan exercise, noting Rep. Liz Cheney, a Republican from Wyoming, agreed to sit on the panel at Pelosi's request. She was absolutely confident that we will have a non-partisan investigation despite being the only Republican remaining on the committee. Behind the scenes, Cheney is also pushing for a Republican to be hired as an outside adviser or panel staff member, sources told CNN. That decision ultimately rests with Pelosi, and staff selections are still ongoing. But even as Republicans attempted to use Wednesday's developments to undermine the committee's credibility, lawmakers across the Democratic caucus have hailed the move. Pelosi's decision, arguing that the investigation should be taken seriously and not turn into a circus. And they argued that the presence of Banks andJordan on the panel would have done just that. Both of them were clearly selected just to be disruptive, and this is not acceptable, said Representative Adam Schiff of California, a Democrat on the select committee who faced Jordan in Trump's first impeachment. Cheney also expressed support for Pelosi's decision, noting that Jordan could be an important witness in the run-up to the insurgency and claiming that Banks had disqualified himself by his comments, especially in the past 24 hours, demonstrating not to take it seriously.
