Climate activist and former Democratic Vice President Al Gore on Sunday said “climate deniers” were comparable to the police officers who failed to act during the mass shooting in Uvalde, Texas.

Appearing as a guest on NBC’s “Meet the Press,” Gore assailed Republicans and tactics like the Senate filibuster for preventing Democrats from passing legislation to tackle global warming. Gore compared “climate deniers” in Congress to police officers who were equipped and trained to deal with mass shooters, but failed to stop the tragedy at Robb Elementary School in Uvalde.

After the Supreme Court overturned Roe v. Wade in its decision in Dobbs vs. Jackson Women’s Health, Sen. Bernie Sanders, the Vermont socialist, put out tweets calling for the codification of Roe v. Wade.

“Overturning Roe v. Wade and denying women the right to control their own bodies is an outrage and in defiance of what the American people want,” said Sanders in a tweet on June 24.

“Democrats must now end the filibuster in the Senate, codify Roe v. Wade, and once again make abortion legal and safe,” he said.

President Biden said Thursday he would support changing the Senate's filibuster rules for Congress to pass a federal law codifying Roe v. Wade.

Why it matters: With the current 60-vote threshold, Democrats have few legislative options to fight the end of the nationwide right to an abortion.

The big picture: Democrats have previously attempted and failed to pass legislation to protect abortion rights on the federal level, and while they have a 50-vote majority in the Senate, such a bill cannot pass unless they change filibuster rules.

President Joe Biden said he would support an “exception” to Senate filibuster rules to codify abortion rights in the wake of the Supreme Court decision repealing the 1973 Roe v. Wade ruling.

“I believe we have to codify Roe v. Wade into law and the way to do that is to make sure Congress votes to do that,” Biden said in Madrid after attending the NATO summit.

“And if the filibuster gets in the way — it’s like voting rights — we should be requiring an exception to the filibuster for this action to deal with the Supreme Court decision,” the president said.

President Joe Biden said Thursday he backs an "exception" to Senate filibuster rules to codify abortion rights.

He called the Supreme Court's decision ending the right to abortion “destabilizing” but said it does not affect U.S. standing on the world stage, as he took credit for modernizing the transatlantic alliance to adapt to new threats from Russia and China.

Several Democratic senators are defending their votes to eliminate the filibuster less than five years after demanding that Republicans keep the procedure.

In a Wednesday vote, 46 Democrats and two Independents moved to ax the nearly 200-year-old filibuster, although they were ultimately unsuccessful in doing so. For 26 of those senators, the vote marked a complete reversal of their 2017 position.

Senate Democrats on Wednesday forced two votes they knew they'd lose on their election bills and the filibuster – breaking a rule often followed by legislators, especially House Speaker Nancy Pelosi, to never call a vote you don't know you'll win. 

The votes mark yet another political loss for President Biden and Democrats. They highlighted the internal divisions among Democrats over the filibuster. And they forced vulnerable Democrats up for reelection to cast a vote Republicans are already attacking them for.

The fight over voting rights has gone from partisan to personal. 

President Biden and his Democratic allies, furious with Republicans for opposing voting rights protections they had embraced for decades, are lashing out across the aisle with racially charged assertions that the GOP would rather secure power than ensure civil rights. 

Senate Democrats failed again to pass sweeping new voting protections on Wednesday, in what may be the most brutal blow yet to efforts to strengthen protections for voters at a perilous moment for US democracy.

Just as they have done four other times in recent months, all 50 Republicans united in their opposition to the measure. They relied on the filibuster, a Senate rule that requires 60 votes to advance legislation to a final vote.

Bernie Sanders suggests he may support primary challengers against Manchin and Sinema

President Biden’s push to rewrite the nation’s voting laws went down to defeat on Wednesday at the hands of a GOP filibuster, leaving Democrats pledging to hold a doomed vote to change the 60-vote threshold.

In a 51-49 vote, the Freedom to Vote Act and the John Lewis Voting Rights failed to garner the 10 GOP votes necessary to pass. Vice President Kamala Harris was on hand to preside over the vote.
