Republicans in the Senate are "ready to mount a filibuster" of legislation creating an independent panel to investigate the Jan. 6 Capitol riot, as GOP opposition to it is "hardening by the day," Politico reports.

Citing interviews with Republicans, Politico writes that there is "almost no path to even opening up debate" on the bill to create the bipartisan commission, let alone a path to actually passing it. Sen. Mike Braun (R-Ind.) told the outlet that "I don't think there will be 10 votes on our side for it" and that he'd "be surprised" if there's "even a handful."

Sen. Joe Manchin (D-W.Va.), who has repeatedly expressed opposition to eliminating the filibuster, in an interview "seemed aghast" that Republicans are set to block the commission, Politico wrote.

"So disheartening," he said. "It makes you really concerned about our country."

Manchin added, when asked if the GOP was abusing the filibuster, that he's "still praying we've still got 10 good solid patriots within that conference."

Senate Minority Leader Mitch McConnell (R-Ky.) earlier this week announced his opposition to the proposal for the commission, arguing the legislation was "slanted and unbalanced." Senate Majority Leader Chuck Schumer (D-N.Y.) has promised, though, that the Senate will vote on creating the commission.

Schumer, Politico writes, plans to bring the bill to the floor while "daring Senate Republicans to block it," and with a GOP filibuster likely, Democrats "see an opportunity to begin making their case to reluctant members that the 60-vote status quo is unsustainable." Sen. Elizabeth Warren (D-Mass), for example, asked, "How do you go forward if you can't make it work over something like an independent commission?" Read more at Politico.
