Harris warns of "unprecedented" sanctions if Russia invades Ukraine

The potential Russian invasion of Ukraine is leading the Munich Security Conference in Germany, an annual event to prevent another war in Europe. 

Addressing the conference on Saturday, U.S. Vice President Kamala Harris said Russia is spreading disinformation, lies and propaganda — and warned of sanctions.

"Let me be clear, I can say with absolute certainty: If Russia further invades Ukraine, the United States, together with our allies and partners, will impose significant, and unprecedented economic costs," she said.
