Bloomberg staying out: Following months of rumors, former New York City Mayor Michael Bloomberg announced that he will not be running for president, The New York Times reports. Entering the contest now, Bloomberg said, would only splinter the race for the Republican nomination, allowing Donald Trump to hold onto his lead.

Another Super Tuesday: Voters head to the polls in primaries in Michigan and Mississippi tomorrow to pick their preferred Democratic and Republican candidates. Republicans will caucus in Hawaii and Idaho. Registered Democrats living abroad will also vote. We’ll be tracking the action.

An unforced error: That’s how tennis star Maria Sharapova has explained her failed drug test at the Australian Open in January.
