A crucial Senate vote on a bill to create an independent inquiry to investigate the deadly January 6 Capitol Hill riot failed Friday, falling short of the 10 Republican votes needed to advance and illustrating GOP efforts to move on from the insurrection that left five people dead and injured 140 police officers.

The vote was 54 to 35, showing the bill had a bipartisan majority of support with six Republicans voting with Democrats. However, the bill needed 60 votes to advance. The six GOP senators who backed the bill were: Mitt Romney of Utah, Susan Collins of Maine, Bill Cassidy of Louisiana, Rob Portman of Ohio, Lisa Murkowski of Alaska and Ben Sasse of Nebraska. Nine Republican senators and two Democrats didn't vote.

The Republican opposition highlights the hold former President Donald Trump still has on most of his party, and underscores the deep partisan divide surrounding the fallout of the attack on the US Capitol, a point Senate Majority Leader Chuck Schumer made following the vote.

The New York Democrat said the Republican minority "just mounted a partisan filibuster against an independent commission to report on January 6."

"This vote has made it official: Donald Trump's 'Big Lie' has now fully enveloped the Republican Party," Schumer added.

The tally of Republican supporters was one fewer than the seven GOP senators who voted to convict Trump at his second impeachment trial earlier this year. Republican Sen. Richard Burr of North Carolina did not vote but had said ahead of Friday that he opposed the bill.

The key vote had been expected as early as Thursday, but due to the order of Senate procedure that vote had to wait until the previous legislation was cleared. Republican senators have delayed overnight passage of a massive bill designed to increase American competitiveness with China, and that means the key procedural vote on a bill to create the January 6 commission has to wait. That impasse was solved Friday morning when senators agreed to bring the vote back up after a one-week recess for the Memorial Day holiday.
