Supporters of a bipartisan commission to investigate the Jan. 6 Capitol riot by former President Donald Trump's supporters made their final arguments before a House of Representatives vote set for Wednesday.
As the Democratic-led House neared the vote, a handful of Republicans joined Democrats in speaking in favor of forming an independent commission modeled after the one that investigated the Sept. 11, 2001, attacks on the United States.
Dealing a significant blow to the chances of congressional passage of legislation establishing a commission, Senate Minority Leader Mitch McConnell announced his opposition, calling it "the House Democrats' slanted and unbalanced proposal" and said existing congressional investigations are sufficient.
In the evenly split Senate - controlled by Democrats only because Vice President Kamala Harris can cast tie-breaking votes - Republicans can block the legislation. At least 60 votes are needed to advance most bills in the 100-member Senate.
