There's a lot of speculation about how Republican senators will respond to the Supreme Court vacancy following the late Justice Ruth Bader Ginsburg's death. Senate Majority Leader Mitch McConnell (R-Ky.) plans to forge ahead with a confirmation vote, and President Trump has urged GOP lawmakers to confirm his nominee "without delay." But observers have pinpointed a few Republicans that could potentially break with the party and try to push the vote until at least after the November election is decided. Sen. Susan Collins (R-Maine), often considered one of the more moderate voices in the upper chamber, was one of them.

Collins, who is in a tough re-election battle, released a statement Saturday, clarifying that she believes a vote to confirm the nominee should wait until after the election. Collins said "we must act fairly and consistently — no matter which political party is in power," likely referring to the fact that the Republican-led Senate blocked then-President Barack Obama's Supreme Court nominee, Merrick Garland, in 2016 due to the proximity to that year's election.

The senator said she would not object if Trump makes a nomination or if the Senate Judiciary Committee begins "the process of reviewing his nominee's credentials," but, ultimately, whoever wins the election on Nov. 3 should make "the decision on a lifetime appointment." Tim O'Donnell

The late Supreme Court Justice Ruth Bader Ginsburg, who died Friday night at 87, was remembered fondly by her eight surviving colleagues on the bench, all of whom released statements on her passing.

Any ideological divide between Ginsburg and the other justices was absent from their recollections, most of which consisted of praise for her intellectual brilliance and positive memories of working alongside her, with multiple justices noting how Ginsburg welcomed them graciously when they took their place on the court. Justice Sonia Sotomayor called Ginsburg a personal "hero" and said she assisted her throughout her career, "long before I came to the Supreme Court."

Former Justice Anthony Kennedy, who retired from the court in 2018, also shared his thoughts, having served alongside Ginsburg for 25 years. "By her learning she taught devotion to the law," he said. "By her dignity she taught respect for others and her love for America. By her reverence for the Constitution, she taught us to preserve it to secure our freedom." Tim O'Donnell

In response to Senate Majority Leader Mitch McConnell's (R-Ky.) plan to give President Trump's eventual nominee to replace the late Supreme Court Justice Ruth Bader Ginsburg a confirmation vote on the Senate floor, possibly before the November election, some Democrats are calling for former Vice President Joe Biden, the Democratic presidential nominee, to threaten to pack, or expand, the high court.

As Jill Filipovich writes in The Washington Post, there is a belief that the GOP would be stealing a Supreme Court seat if enough lawmakers change their stance on whether a president should nominate a Supreme Court justice in an election year. McConnell and the Republican Senate, Filipovich writes, "have so repeatedly broken the rules, rigged the game, and stolen victories that it's become impossible to play on neutral turf," which is why she thinks Democrats should at least consider embracing the controversial tactic.

Filipovich notes the court hasn't always had nine members and suggests a Biden White House and Democratic-controlled Congress could sign and pass an act rather easily. But Biden has repeatedly said he's not in favor of the move because "we'll live to rue that day." Additionally, other analysts doubt court-packing will catch on with the majority of Democratic voters, and especially swing voters.

Indeed, there's even a sense that pushing for court expansion could backfire quickly. Tim O'Donnell

The battle over Supreme Court Justice Ruth Bader Ginsburg's now-vacant seat was already in full swing just hours after it began.

Senate Majority Leader Mitch McConnell (R-Ky.) made it clear he wants to fast-track the confirmation of Ginsburg's replacement and said President Trump's nominee will receive a vote on the Senate floor. The president, for his part, said Republicans have an "obligation" to confirm his nominee, whoever it may be, "without delay."

But Democrats also made their position clear. In the 9 p.m. ET hour on Friday, after Ginsburg's death was announced, donors gave $6.2 million online to Democratic causes. That's the most money ever given in a single hour since ActBlue, the party's donation-processing site launched 16 years ago, The New York Times reports. Then, in the 10 p.m. hour, Democratic donors set another record by giving $6.3 million.

ActBlue doesn't specify where donations go in real time, but one page created by Crooked Media — a media company set up by former Obama administration aides and home to the Pod Save America podcast — called "Get Mitch or Die Trying" (in reference to McConnell) raised more than $3 million in about three hours, the Times reports, and was headed toward $13 million as of Saturday afternoon (at that time, ActBlue had processed $46 million overall since Ginsburg's death.) The proceeds will be divided among 13 different Democrats running for Senate this year. Read more at The New York Times. Tim O'Donnell

That didn't take long.

President Trump on Saturday urged Senate Republicans to confirm a new Supreme Court Justice, who he will nominate, to replace the late Justice Ruth Bader Ginsburg, who died Friday night at 87. Trump told GOP lawmakers "we have this obligation, without delay."

Ginsburg's death has already sparked a debate over the vacant seat. In 2016, Senate Republicans blocked then-President Barack Obama's nominee, Merrick Garland, because it was an election year. So is 2020, but Senate Majority Leader Mitch McConnell (R-Ky.) has argued it's a different situation because the Senate majority and president are from the same party and, therefore, he is aiming to fast-track a nomination. Democrats — and some Republicans — have said a confirmation hearing should wait until at least after the November election, if not January's inauguration.

Days before she died, Ginsburg reportedly said her "most fervent wish is that I will not be replaced until a new president is installed." With Trump and McConnell on the same page about confirming her replacement as soon as possible, it appears whether her wish is granted will depend on how individual Republican senators approach the situation.

Russian opposition leader Alexei Navalny on Saturday posted a photo to his Instagram account in which he is walking down a flight of stairs as part of his recovery after he was poisoned last month.

In the photo's caption, Navalny, one of Russia's most prominent Kremlin critics, wrote that he has a "clear path" to recovery, but suggested it will be a long one. He was removed from a ventilator five days ago and said he is still having trouble climbing stairs, pouring water, and using his phone. Still, he has apparently made significant progress since, he said, he was previously considered only "technically alive."

Navalny fell ill in August while in Siberia and was airlifted to a hospital in Berlin while in a coma. Multiple labs in Europe have confirmed he was poisoned by a Soviet-era nerve agent called Novichok. His supporters suspect Russian President Vladimir Putin was behind the assassination attempt, but Moscow has denied any involvement and has accused Navalny's aides of removing evidence, jeopardizing the official inquiry into the poisoning.
