Nearly uniform Republican opposition in the Senate on Sunday stripped a proposed cap on insulin prices in private insurance from Democrats' party-line climate, health and tax bill.

Democrats had sought to overrule a decision from the Senate rules official, the parliamentarian, that a $35-per-month limit on insulin costs under private insurances did not comply with the budget reconciliation process, which allowed Democrats to pass their bill with a bare majority.

The cap, which was proposed by Sen. Raphael Warnock, D-Ga., needed 60 votes to pass and remain in the Inflation Reduction Act (IRA). It ultimately failed by a 57-43 vote.

Republicans Bill Cassidy of Louisiana, Susan Collins of Maine, Josh Hawley of Missouri, Cindy Hyde-Smith of Mississippi, John Kennedy of Louisiana and Alaska's Lisa Murkowski and Dan Sullivan voted for the measure with Democrats. All 43 "no" votes came from Republicans.

The cap's scrapping was quickly seized on by Democrats and stirred controversy beyond them, with critics of the GOP citing the sometimes startling cost of needed insulin for diabetics.

Republicans, in turn, accused Democrats of being misleading about a vote that they said amounted to a technicality rather than a policy difference.
