United States President Joe Biden highlighted his administration’s efforts to curb gun violence during a visit to New York City also aimed at projecting a united front with Mayor Eric Adams after a series of violent crimes that has rattled the city.

Biden and U.S. Attorney General Merrick Garland made the trip in the wake of the funerals of two city police officers who were fatally shot last month while responding to a 911 call.

"Enough is enough because we know we can do things about this, but for the resistance we're getting from some sectors of the government and the Congress and the state legislatures and organizational structures out there," said Biden.

The police killings are part of an overall surge in gun violence in U.S. cities, including Philadelphia and Chicago, since the beginning of the coronavirus pandemic in 2020.

With more guns than people, the U.S. is by far the most heavily armed society in the world, and sales to first-time buyers skyrocketed in 2020.

The White House and Democrats are pushing back on Republican accusations that the party is weak on crime before critical midterm elections in November.

"We're not about defunding we're about funding," Biden said, explicitly rejecting the "defund the police" idea pushed by some Democrats after the 2020 killing of George Floyd, and added he was asking for more funding for communities and community police.

Biden touted the administration's five-part plan unveiled in June that sought to stem the flow of firearms and invest in police resources. He also announced new efforts, such as targeting gun trafficking from southern states to the U.S. Northeast and getting repeat gun offenders off the streets.

"This doesn't violate anybody's Second Amendment right," said Biden. "There's no amendment that's absolute. You couldn't buy a cannon when this amendment was passed. There's no reason why you should be able to buy certain assault weapons," he added.

The Justice Department is also expected to announce new efforts to crack down on so-called ghost guns, unregistered and untraceable homemade weapons that can be made with a 3D printer.

From January 2016 to the end of 2020, there were 23,906 suspected ghost guns reported to the Bureau of Alcohol, Tobacco, Firearms and Explosives, including 325 used in homicides, or attempted homicides, a senior administration official said.

Biden first traveled to New York police headquarters to join a meeting of the gun violence strategic partnership, which meets five days a week to share intelligence and develop plans. He will then go to a school to meet community leaders to talk about prevention.

Biden's visit to the country's biggest city will be his first since Adams was sworn in as mayor at the beginning of the year. A former police officer, Adams centered his campaign on improving public safety and spoke enthusiastically about working with Biden.

"The president is here because he knows what the American people want: Justice, safety and prosperity," Adams said and added he shared the sentiment.

There is a reason "they call me the Biden of Brooklyn" Adams said, pledging to stand "shoulder to shoulder" with the president.
