WASHINGTON — Top Democratic leaders in the Senate say the Republican policing bill  is "not salvageable," as they signal an intent to block it and demand negotiations on a new, more bipartisan package in response to the killing of Black Americans.

That's according to a letter to Senate Majority Leader Mitch McConnell from the Democrats obtained by The Associated Press.

"This bill is not salvageable and we need bipartisan talks to get to a constructive starting point," write Democratic leader Chuck Schumer and the co-authors of the party's bill, Sen. Kamala Harris, D-Calif., and Sen. Cory Booker, D-N.J.

The Republican legislation would create a national database of police use-of-force incidents, restrict police chokeholds and set up new training procedures. It is not as sweeping as a Democratic proposal, but has similar provisions.

The opposition from Democrats is being backed by the nation's leading civil rights organizations and the lawyer, Benjamin Crump, representing the families of George Floyd  and Breonna Taylor, two African Americans whose deaths in police interactions sparked worldwide protest over law enforcement procedures.

Crump said in a statement, "The Black community is tired of the lip service." 

He said the GOP package is "in direct contrast to the demands of the people, who have taken to the streets, to call for the reallocation of resources in order to improve social safety nets and public mental health programs."

The NAACP Legal Defense and Fund is urging senators to vote against advancing the GOP package. The procedural vote is set for Wednesday.

"In this moment, we cannot support legislation that does not embody a strong accountability framework for police officers and other law enforcement who engage in misconduct as well as needed reforms to policing practices," the organization wrote to senators, according to a letter obtained by AP.

McConnell is pushing ahead with the Justice Act in a test vote Wednesday, but without Democratic backing the bill is not expected to reach the 60-vote threshold needed to advance.

"We're ready to make a law, not just make a point," McConnell said as he opened the Senate on Tuesday. He said Americans "deserve better than a partisan stalemate."

McConnell said, "We'll find out whether our Democratic colleagues share our ambition or whether they chose to duck the issue and leave the country in the lurch."

Congress is under enormous pressure to establish new oversight and accountability of the police as demonstrations spill into cities large and small nationwide.
