Senate Republicans on Friday blocked legislation to form a commission to probe the Jan. 6 attack on the Capitol.
Senators voted 54-35 on the House-passed bill, falling short of the 10 GOP votes needed to get it over an initial hurdle and marking the first successful filibuster by Republicans in the 117th Congress.
GOP Sens. Lisa Murkowski (Alaska), Mitt Romney (Utah), Susan Collins (Maine), Bill Cassidy (La.), Rob Portman (Ohio) and Ben Sasse (Neb.) broke ranks and voted to advance the legislation.
