Students in every corner of the U.S. have designated today National Walkout Day and marched out of their classrooms to protest gun violence on American campuses.

The big picture: Students from Los Angeles to Charlottesville showed power in numbers and demanded action from lawmakers on the one-month anniversary of the tragic mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida.

Mary Trump book: How she leaked Trump financials to NYT

Simon & Schuster

In her new memoir, President Trump's niece reveals how she leaked hordes of confidential Trump family financial documents to the New York Times in an effort to expose her uncle, whom she portrays as a dangerous sociopath.

Why it matters: Trump was furious when he found out recently that Mary Trump, a trained psychologist, would be publishing a tell-all memoir.

Brazilian President Jair Bolsonaro announced Tuesday that he tested positive for coronavirus.

Why it matters: Brazil's coronavirus outbreak is one of the largest in the world, topped only by the U.S., and Bolsonaro has long downplayed the effects of the virus, pushing businesses to reopen over the last few months in order to jumpstart the country's economy.
