(CNN) Legislation moved quickly through Congress this week to establish June 19 as Juneteenth National Independence Day, a US federal holiday commemorating the end of slavery in the United States.
The bill overwhelmingly passed the House on Wednesday after the Senate unanimously passed the legislation on Tuesday.
But at the same time, key legislation aimed at countering racial inequity and discriminatory policies faces major obstacles on Capitol Hill.
A number of stumbling blocks have complicated efforts to strike a bipartisan deal on policing legislation after George Floyd's death in police custody in 2020 sparked nationwide calls to overhaul policing and address police misconduct and racial injustice.
Democrats also face a divide within their ranks and stiff GOP opposition to a sweeping voting and elections bill they have made a signature agenda item and argue is needed to counter state-level Republican efforts to restrict voting access.
The Democrat-led House of Representatives passed legislation in March aimed at preventing police misconduct that Democrats named in honor of George Floyd. But there is not yet a clear path forward over the issue in the Senate, where police overhaul legislation would need at least 10 Republican votes to pass.
A bipartisan group of lawmakers, led by GOP Sen. Tim Scott of South Carolina, Democratic Sen. Cory Booker of New Jersey and Rep. Karen Bass of California, has been in talks for months in an effort to find consensus between the two parties and strike a deal that could pass in the Senate. The group has reported progress along the way, but a deal still has yet to materialize and it is not clear if the effort will succeed or stall out.
Bipartisan talks have recently been hung up on a key issue: Whether Congress should include new standards for when officers can be charged with crimes.
Democrats have proposed adding new crimes for which officers can be charged, something they argue will increase officer accountability. Scott and Republicans remain steadfast that any change to Section 242 -- the standard for criminally prosecuting police officers -- is a red line, so any addition of new crimes would have to exist outside of that provision.
Scott said on Thursday that he is open to "continuing the conversation" about adding specific additional crimes outside excessive force for which police officers can be charged, a new development in the ongoing negotiations. Sen. Lindsey Graham, the other South Carolina Republican, said this week they were open to adding crimes like sexual assault.
"I think there is an important consideration that needs to be had about improving the confidence that the communities have to law enforcement's response and when you see areas that are easily identifiable, should you solve those issues, the answer is you should," Scott told CNN.
The issue is separate from another sticking point: Whether to change the so-called qualified immunity standard to make it easier to sue officers in civil court.
Despite the issues negotiators still must resolve, the lawmakers have sounded optimistic about the prospect that they will get a deal sometime this month.
"I'm still optimistic this is the month that it has to happen," Scott said.
"I do still think we can wrap things up this month," Bass said. "And if we have to go into July a little bit, we go into July, but there's no reason for this to last until the August recess."
Efforts by Democrats to enact voting overhaul legislation face multiple hurdles in Congress, specifically in the Senate.
President Joe Biden has urged Democrats to pass the For the People Act and the John Lewis Voting Rights Advancement Act to protect voting access and roll back discriminatory moves against minority voters.
But Democrats do not have the 60 votes necessary to pass either piece of legislation in the Senate, the threshold needed to overcome a legislative filibuster.
Republican senators have widely panned the For the People Act, a sweeping bill that Democrats say will expand voting access and counter efforts to restrict the right to vote at the state level. Republicans, on the other hand, call the legislation a partisan power grab and a federal overreach into state voting and election systems.
Democrats have faced internal divisions over the For the People Act with West Virginia Sen. Joe Manchin saying earlier this month that he would not vote for the bill, and arguing that any major voting legislation must be enacted on a bipartisan basis.
In response, Senate Democrats have engaged in a quiet courtship of Manchin in an attempt to garner unified party support for the legislation. On Wednesday, Manchin left open the option that he could support a modified bill.
Former Georgia gubernatorial candidate and voting rights advocate Stacey Abrams on Thursday praised Manchin's proposed changes, a notable statement of support from someone who is widely seen as a leader among progressives on the issue.
"What Sen. Manchin is putting forward are some basic building blocks that we need to ensure that democracy is accessible, no matter your geography," Abrams, a Democrat and strong advocate for voting rights, said on CNN's "New Day."
Manchin is trying to more narrowly tailor the bill so that it is pared back and focused on compromise. The West Virginia Democrat on Wednesday released a proposal that would make Election Day a holiday, ban partisan gerrymandering, mandate at least 15 consecutive days of early voting and institute a voter ID requirement.
A test vote on the voting bill is expected to take place next Tuesday, and Democrats are scrambling to try to get Manchin's support before then so that they can put up a unified front against Republican opposition to the measure. It's not yet clear if that will happen, however.
The vote would be to break a filibuster to open debate and would require the support of 60 senators, which it does not currently have.
But even if Manchin were to back the legislation, it is still virtually guaranteed to lack the GOP support to pass in the Senate.
Senate Minority Leader Mitch McConnell made that clear on Thursday by throwing cold water on Manchin's revised proposal and indicating that he did not believe any Republican in the Senate would vote for it.
"There's now a debate among Democrats over a revised version produced by one of the Democrats yesterday which has been endorsed by Stacey Abrams," McConnell said.
He went on to call the proposal, "Equally unacceptable. Totally inappropriate," and said, "All Republicans, I think, will oppose that as well."
The John Lewis voting rights legislation has garnered some bipartisan support, but has still not picked up the votes to pass in the Senate, where Democrats control the narrowest possible majority with a 50-50 partisan split. Republicans have largely dismissed the need for the legislation to restore a key part of the landmark Voting Rights Act.
