Sen. Bernie Sanders sent a message to Russian President Vladimir Putin on the debate stage Tuesday, stating, "If I'm president of the United States, trust me, you're not going to interfere in any more American elections."

The big picture: It was unveiled last week that Russia has been interfering to boost Sanders' campaigns in an apparent attempt to strengthen President Trump's bid for re-election. Former New York Mayor Mike Bloomberg said, "Vladimir Putin thinks that Donald Trump should be president of the United States, and that's why Russia is helping [Sanders] get elected."

  • Competitors for the Democratic nomination targeted Sanders on Tuesday. He's the front-runner and has gained momentum in South Carolina ahead of the state's primary Saturday.

The second jobs apocalypse

This week, United Airlines warned 36,000 U.S. employees their jobs were at risk, Walgreens cut more than 4,000 jobs, Wells Fargo announced it was preparing thousands of terminations this year, and Levi's axed 700 jobs due to falling sales.

Why it matters: We have entered round two of the jobs apocalypse. Those announcements followed similar ones from the Hilton, Hyatt, Marriott and Choice hotels, which all have announced thousands of job cuts, and the bankruptcies of more major U.S. companies like 24 Hour Fitness, Brooks Brothers and Chuck E. Cheese in recent days.
