Mike Bloomberg's campaign said Friday that vandalism at its Knoxville, Tenn., office "echoes language from [Bernie Sanders'] campaign and its supporters," even as it admitted that it didn't know who was responsible.

Why it matters: It marks a massive escalation in the war of words between the two Democratic presidential candidates that has spilled into the open over the last week — covering everything from their heart health to debate performances to electability.

What happened: The Tennessee office had profanities spray painted across its glass doors — along with posters reading Authoritarian," "Classist" and "Oligarch" placed on its windows, per Knox News.

What they're saying: "We don't know who is responsible for this vandalism, but we do know it echoes language from the Sanders campaign and its supporters," Bloomberg campaign manager Kevin Sheekey said in a statement.

  • "Over the past week, we've seen similar attacks against Mike Bloomberg 2020 offices in multiple states. Fortunately, no one has been injured. But this needs to end before someone gets hurt."
  • "We call on Bernie Sanders to immediately condemn these attacks and for his campaign to end the Trump-like rhetoric that is clearly encouraging his supporters to engage in behavior that has no place in our politics."

The big picture: The list of 53 countries was not initially published along with the statement, but has been obtained by Axios. It is made up primarily of autocratic states, including North Korea, Saudi Arabia, Syria and Zimbabwe.

More analysts are making the case that COVID-19 could be an inflection point for oil use and carbon emissions, but it's hardly one that puts the world on a sustainable ecological path.

Driving the news: The risk advisory firm DNV GL, citing the pandemic's long-term effects on energy consumption, projects in a new analysis that global CO2 emissions "most likely" peaked in 2019.

U.S. economy added 4.8 million jobs in June

The U.S. economy added 4.8 million jobs last month, while the unemployment rate dropped to 11.1% from 13.3% in May, according to government data released Thursday.

The state of play: While the labor market showed more signs of recovery when the government’s survey period ended in early June, the lag means that more recent developments, like the surge in coronavirus cases and resultant closures in some states, aren't captured in this data.
