WASHINGTON (AP) -- All but conceding defeat, President Joe Biden said Thursday he's now unsure the Democrats' major elections and voting rights legislation can pass Congress this year. He spoke at the Capitol after a key fellow Democrat, Sen. Kyrsten Sinema of Arizona, dramatically announced her refusal to go along with changing Senate rules to muscle the bill past a Republican filibuster.
Biden had come to the Capitol to prod Democratic senators in a closed-door meeting, but he was not optimistic when he emerged. He vowed to keep fighting for the sweeping legislation that advocates say is vital to protecting elections.
"The honest to God answer is I don't know whether we can get this done," Biden said. He told reporters, his voice rising, "As long as I'm in the White House, as long as I'm engaged at all, I'm going to be fighting."
Sinema all but dashed the bill's chances minutes earlier, declaring just before Biden arrived on Capitol Hill that she could not support a "short sighted" rules change.
She said in a speech on the Senate floor that the answer to divisiveness in the Senate and in the country is not to change filibuster rules so one party, even hers, can pass controversial bills. "We must address the disease itself, the disease of division, to protect our democracy," she said.
The moment once again leaves Biden empty-handed after a high-profile visit to Congress. Earlier forays did little to advance his other big priority, the "Build Back Better Act" of social and climate change initiatives. Instead, Biden returned to the White House with his agenda languishing in Congress.
Biden spoke for more than an hour in private with restive Democrats in the Senate, including Joe Manchin of West Virginia, who also opposes changing Senate rules.
Manchin said in a statement later: "Ending the filibuster would be the easy way out. I cannot support such a perilous course for this nation."
Both senators went to the White House Thursday evening for an additional hour, which the White House later described as "a candid and respectful exchange of views."
Since taking control of Congress and the White House last year, Democrats have vowed to counteract a wave of new state laws, inspired by former President Donald Trump's false claims of a stolen election, that have made it harder to vote. But their efforts have stalled in the narrowly divided Senate, where they lack the 60 votes out of 100 needed to overcome a Republican filibuster.
For weeks, Sinema and Manchin have come under intense pressure to support rules changes that would allow the party to pass their legislation with a simple majority -- a step both have long opposed.
Senate Minority Leader Mitch McConnell, R-Ky., called Sinema's speech an important act of "political courage" that could "save the Senate as an institution." Her own colleagues weren't as charitable.
Sen. Angus King, a Maine independent who once opposed changing the Senate rules said, "She believes that the risk of changing the filibuster is greater than the risk of what's going on in the states. I hope profoundly that she's right. I fear that she's wrong."
The Democratic package of voting and ethics legislation would usher in the biggest overhaul of U.S. elections in a generation, striking down hurdles to voting enacted in the name of election security, reducing the influence of big money in politics and limiting partisan influence over the drawing of congressional districts. The package would create national election standards that would trump the state-level GOP laws. It would also restore the ability of the Justice Department to police election laws in states with a history of discrimination.
Biden's trip to the Capitol, where he served for decades as a senator from Delaware, was part of weeklong effort to jolt the stalled legislation. On Tuesday he gave a fiery speech in Atlanta, likening opponents of the legislation to racist historical figures and telling lawmakers they will be "judged by history."
Republicans are nearly unanimous in opposing the legislation, viewing it as federal overreach that would infringe on states' abilities to conduct their own elections. And they've pointed out that Democrats opposed changes to the filibuster that Trump sought when he was president.
But for Democrats and Biden, the legislation is viewed as a political imperative. Failure to pass it would break a major campaign promise to Black voters, who helped hand Democrats control of the White House and Congress, and would come just before midterm elections when slim Democratic majorities will be on the line.
During the closed-door meeting, Biden and the senators engaged in a spirited conversation, the president drawing on his own years in the chamber, senators said. He fielded questions and comments, including from Manchin, who expressed reluctance to changing Senate rules. Biden's message to the senators: It's an "opportunity to do something that will do so much good for so many at a time where it's so necessary," according to Sen. Tim Kaine, D-Va.
Democrats have still pledged to force a public showdown over the bill on the Senate floor, which could stretch for days and carry echoes of civil rights battles a generation ago that led to some of the most famous filibusters in Senate history.
Senate Majority Leader Chuck Schumer had initially set Monday's Martin Luther King Jr. holiday as a deadline to either pass the voting legislation or consider revising the filibuster rules. But after one Democratic senator tested positive for COVID-19 and went into isolation, denying the party a needed vote, Schumer canceled a planned Senate recess week and said debate would instead begin Tuesday.
Democrats shifted their legislative strategy, too, as they sought to pressure Manchin and Sinema. Under their new approach, which uses a procedural shortcut, they will be able to debate the bill without being blocked by a filibuster -- a feat after Republicans used the filibuster four times in recent months to stop deliberation.
The mechanics work like this: The House amended and passed an unrelated bill that was already approved by both chambers of Congress, combining Democrats' voting proposals into one bill. Because that bill already passed both chambers, it can be called for debate in the Senate with a simple majority, though Senate Republicans can still block a final vote to pass the measure.
"Members of this chamber were elected to debate and vote, particularly on an issue as vital to the beating heart of democracy as this one," Schumer said late Thursday.
Democratic Sen. Raphael Warnock questioned the wisdom of Manchin and Sinema's reflexive pursuit of bipartisanship.
"It can't be the only important thing," said Warnock, who is Georgia's first Black senator. "Slavery was bipartisan. Jim Crow segregation was bipartisan. The denial of women's suffrage was bipartisan."
