WASHINGTON -- Furious Senate Democrats vowed Tuesday to vote on legislation to protect abortion access for millions of Americans, but without broader support from Republicans, Congress is essentially powerless to prevent the unraveling of the landmark Roe v. Wade ruling.

Amid fallout from , said the conservative justices 鈥渓ied鈥 to the Senate during confirmation hearings when they assured senators the case that since 1973 has allowed abortion access was settled law.

And two Republican senators who publicly support abortion access, Lisa Murkowski of Alaska and Susan Collins of Maine, but have voted to confirm conservative justices vented their frustrations at the court's draft document and pushed their own bill to turn the Roe v. Wade ruling into law.

鈥淭he Supreme Court is poised to inflict the greatest restriction of rights in the past 50 years - not just on women, but on all Americans,鈥 Schumer said.

Murkowski told reporters on Capitol Hill that if the direction of the draft becomes the final opinion, 鈥淚 will just tell you that it rocks my confidence in the court right now.鈥

The Congress, however, can do little to stop the court from undoing Roe v. Wade unless more Republicans join Democrats in voting to protect abortion access, which is almost certainly unlikely. Schumer said the Senate would vote next week on emerging legislation, but facing a certain filibuster by Republicans, the Democrats signaled they prefer to fight over the issue on the campaign trail this fall, rather than in Congress. The House is away this week.

Republicans have spent decades laser-focused on the high court, installing conservative justices intent on revisiting abortion and other social issues, including three ushered to confirmation by Senate GOP Leader Mitch McConnell during Donald Trump's presidency to build the court's solid 6-3 majority.

Typically reveling in his role as the architect of the conservative Supreme Court majority, McConnell demurred Tuesday when asked if he took credit for engineering a decision that would end the constitutional right to an abortion for millions of women.

Instead, McConnell, R-Ky., said the focus should be on getting to the bottom of the

鈥淚 think the story today is the effort by someone on the inside,鈥 McConnell said of the leak.

Schumer shot back that Republicans are afraid to own what they have brought because 鈥渢hey are on the wrong side of history.鈥

Passing an abortion access bill through the Senate remains a political longshot, especially under the rapid timeline that would be needed before the Supreme Court issues its final decisions in June.

Schumer stopped short of promising to change Senate filibuster rules to allow Democrats to overcome Republican obstruction and pass legislation that would salvage the landmark abortion law on their own, as some party advocates are demanding.

The Democratic leader does not have the votes within the Democrats' razor-thin 50-vote majority to muscle through a rules change in the Senate that would allow Democrats to push past what is typically a 60-vote threshold on big bills.

The political fallout in Congress is certain to be far-reaching and complicated, a gripping new phase in the partisan fights over abortion access, religious liberties and the fundamental aspects of women's reproductive health.

The Republican senators in particular, who helped turn the court into a solid 6-3 conservative majority, face deep scrutiny over their public beliefs at the time and the reality now confronting the country.

Collins pointed blame back to the justices themselves, personally singling out two of the three Trump-era judges, Neil Gorsuch and Brett Kavanaugh, she had supported for confirmation.

The Maine Republican said if the leaked draft opinion on abortion becomes the ruling of the court, 鈥渋t would be completely inconsistent with what Justice Gorsuch and Justice Kavanaugh said in their hearings and in our meetings in my office.鈥 She did not vote for another Trump-nominated justice, Amy Coney Barrett, because confirmation came so close to the 2020 election.

Murkowski, who is up for reelection this year, did not vote for Kavanaugh after his explosive confirmation hearings over allegations he sexually assaulted a woman acquaintance during high school. She did give her support to Gorsuch and Barrett.

Other Republican senators slammed the unusual leak of the high-profile draft opinion as an attempt to bully the court, even as they celebrated its contents. Chief Justice John Roberts, confirming the authenticity of the leaked draft opinion, on Tuesday ordered an investigation into the leak.

Sen. Josh Hawley, R-Mo., said the leaked draft from Justice Samuel Alito 鈥渋s a really good opinion.鈥

Hawley said he looked forward to the campaign debate. 鈥淭he people will really get to weigh in,鈥 he said.

Crowds gathered at the Supreme Court, which sits across the street from the Capitol and can be seen from the House and Senate. Anti-abortion rights protesters carried signs that said 鈥淚gnore Roe鈥 while their pro-abortion-rights counterparts held placards declaring 鈥淏ans off our Bodies鈥 and 鈥淚mpeach Kavanaugh.鈥

One pivotal Democrat, Sen. Joe Manchin of West Virginia, who talks frequently with McConnell, declined to weigh into the debate - or whether he would be willing to rethink his opposition to changing filibuster rules. He has been a holdout denying Democrats of the 51 votes needed to change the rules.

鈥淟et's wait to see everything,鈥 Manchin said.

But Sen. Elizabeth Warren, D-Mass., countered McConnell and the other Republicans who want to go after the leak. 鈥淲hat should be investigated and prosecuted is the fact that people who were nominated to the Supreme Court stood up and said they believed in the rule of law and precedent, and then at first opportunity, changed direction by 180 degrees and are going for a full repeal of Roe,鈥 said Warren, a former Harvard law professor.

Trump was able to nominate and have the Senate confirm three justices, engineering a wholesale revamping of the high court, now with a solid conservative majority.

As GOP leader, McConnell stunned Washington at the start of the 2016 presidential campaign season when he refused to allow the Senate to consider then-president Barack Obama's nominee, Merrick Garland, for a high court vacancy, holding the position open until Trump won election to become president that fall.

McConnell then marshalled into place a Senate rules change to enable Republicans to bypass a Democratic filibuster and approve Supreme Court nominees on a simple 51-vote threshold - going further than Democrats had done on their own earlier rules change to allow majority confirmation of lower-level posts.
