Russia and Ukraine engaged in a brief skirmish this morning — on Twitter, in English.

The beef: The countries argued over the nationality of Anna Yaroslavna, the queen consort of France from 1051 to 1060. She was born in Kievan Rus — a connected group of Slavic tribes from which some modern nations, including both Russia and Ukraine, claim their cultural ancestry. So to Ukrainians, she's "Anne of Kiev," and to Russians, she's "Anne of Russia."

Why it matters: It's just another arm of the all-out propaganda war between Russia and Ukraine following Russia's illegal seizure of Crimea. Plus, the statement "comply with int law" between two countries is all the more devastating when it's delivered with a Benedict Cumberbatch GIF.

Primary elections are being held on Tuesday in Minnesota, Georgia, Connecticut, Vermont and Wisconsin.

The big picture: Georgia and Wisconsin both struggled to hold primaries during the coronavirus pandemic, but are doing so again — testing their voting systems ahead of the general election. Rep. Ilhan Omar (D-Minn.) is facing a strong challenger as she fights for her political career. In Georgia, a Republican primary runoff pits a QAnon supporter against a hardline conservative.

The U.S. government has agreed to buy 100 million doses of Moderna's experimental coronavirus vaccine for $1.5 billion, or $15 per dose.

Why it matters: The Trump administration, through Operation Warp Speed, has now bought initial batches of vaccines from Moderna, GlaxoSmithKline and Sanofi, Pfizer, Novavax, Johnson & Johnson and AstraZeneca before knowing whether they are safe and effective. The federal government also appears to own some of the patent rights associated with Moderna's vaccine.
