1. Democratic presidential candidate Bernie Sanders pulled off a stunning upset in the Michigan primary on Tuesday night. Sanders defeated Democratic frontrunner and former Secretary of State Hillary Clinton.

2. Maria Sharapova failing an Australian Open doping test for a substance banned only weeks before was "reckless beyond description," former World Anti-Doping Agency (WADA) president Dick Pound said. The Russian, a five-time Grand Slam singles champion, revealed Monday she tested positive for the banned substance meldonium in January.

3. Bank of England Governor Mark Carney was accused of "making speculative pro-EU statements" that were "beneath the dignity of the BOE" by Conservative MP and Eurosceptic Jacob Rees-Mogg on Tuesday. Carney told Rees-Mogg he was "not going to let that stand."
