House Speaker Nancy Pelosi (D., Calif.) admitted Thursday that she does not have the votes to pass a public-safety bill, a blow to vulnerable Democrats who are trying to run against accusations that the party wants to defund the police.

Pelosi canceled a planned vote this week on a bill that would fund grant programs for local police departments to hire additional police officers.

The policies were introduced by two vulnerable Democrats, Reps. Abigail Spanberger (Va.) and Josh Gottheimer (N.J.). But other Democrats and left-wing activist groups bristled at the proposals.

The Congressional Black Caucus opposed extra funding for police departments, citing alleged shootings of unarmed black men.

Other interest groups, such as the Leadership Conference on Civil and Human Rights, chaired by “defund the police” proponent Maya Wiley, called the proposals part of a “discriminatory criminalization-first approach to public safety.”

Those disagreements led Pelosi to cancel a vote because she lacked enough Democratic “yeas.”

The bill’s failure presents a critical blow to vulnerable Democrats fighting back against accusations that their party is anti-law enforcement.
