In the audio, reportedly from a 2015 speech in Colorado, Bloomberg also claims that "95%" of "murders and murderers and murder victims" are male minorities between the ages of 16 to 25.
Bloomberg was the mayor of New York City from 2002 to 2013. And, that's where the real crime is.
The three-term NY mayor goes on to advise blanketing minority neighborhoods with cops - once again, because "that's where the crime is" - and says the way to get guns off the streets is to "throw [minority youth] against the wall and frisk them".
As he launched his campaign for the Democratic presidential nomination previous year, Mr Bloomberg sought to draw a line under the controversy over policing tactics he championed while he was the Republican mayor of New York City from 2002-13.
None of his Democratic rivals has yet to truly capitalize, though both Bloomberg and Bernie Sanders have made some inroads.
"And they say, 'Oh, I don't want that, I don't wanna get caught.' So they don't bring the gun", he says. As a result, New York City police piled into minority neighborhoods making millions of stops targeting black and brown young men in the name of deterrence.
The audio, released on Monday, was recorded when Bloomberg spoke at the Aspen Institute in 2015. That's true in virtually every city in America.
Some Trump advisers have privately expressed concern about Bloomberg as a potential threat to Trump's re-election because of his ability to spend massively from his personal fortune. To combat crime, he says, "put a lot of cops where the crime is, which means in minority neighborhoods".
Trains, flights and ferries disrupted in aftermath of Storm Ciara
Weather warnings have been rife this week - with a snow and ice warning issued for Greater Manchester tomorrow (February 13), too. The damage to homes and cars caused by storm Ciara over the weekend could go up to around €150m, insurers estimated on Tuesday.
"Bloomberg's broken windows policing absolutely created the culture of racial profiling that led to Black Americans being disproportionately accosted by the police", said Dixon.
What does Bloomberg say now about "stop and frisk"?
The "stop and frisk" policy encouraged police to stop and search pedestrians and targeted disproportionate numbers of African-American and Hispanic people. But as we know, good intentions aren't good enough.
Bloomberg campaign state director Aaron Pickrell, who previously served in the same capacity for President Barack Obama's 2008 campaign, said the staff and leadership team is composed mostly of OH natives, giving Bloomberg an organizing edge for the March 17 primary election.
"I can't change history", he told the congregation. Parscale told aides recently that the campaign would soon be doing more Bloomberg-centric polling, according to a campaign aide not authorized to speak publicly about private conversations.
Pundits were sceptical of his plan, though his steady rise in the polls has appeared to prove them wrong.
