What the hell is going on in Argentina?

1. Argentina's insane presidential scandal A draft for an arrest warrant for Argentinian President Cristina Fernández de Kirchner was found at an Argentinian prosecutor's home, shortly after he was found dead under mysterious circumstances. [New York Times / Simon Romero] It's unclear if Alberto Nisman, the deceased prosecutor, intended to execute the warrant. [Vox / Amanda Taub] Prior to his death, Nisman had traced the 1994 suicide bombing of a Buenos Aires Jewish center to Iranian agents. [New York Times / Jonathan Gilbert and Simon Romero] Nisman's death initially looked like a suicide — but although the gun that killed him was found by his body, Nisman's hands had no gunshot residue. [Wall Street Journal / Taos Turner and Santiago Perez] Nisman publicly accused President Kirchner of colluding with Iran to derail the investigation in exchange for access to oil. [Reuters / Brian Winters and Nicolás Misculin] A judge declined to hear Nisman's indictment of Kirchner, which many analysts concluded was deeply flawed. [The Guardian / Jonathan Watts] Kirchner initially referred to Nisman's death as a suicide, but later reversed herself to say it "was not a suicide" in a statement. [Vox / Amanda Taub] Kirchner announced a bill to disband the country's intelligence service and replace it with a new one shortly after reversing her stance on Nisman's death.

Vaccine controversies continue The Centers for Disease Control and Prevention is worried that the US measles outbreak, which already hit at least 14 states, could grow. [The Hill / Kristina Wong] A Republican congressman suggests maybe you should blame immigrants for measles. [Vox / Dara Lind] Any measles outbreak could be prevented through vaccines, but most states have broad exemptions for childhood vaccination requirements. [Vox / Sarah Kliff] Don't know why you should worry about measles? For one, it's one of the most contagious diseases on the planet. [Vox / Julia Belluz] The debate over whether vaccines should be required has spilled over to the 2016 presidential race. [PBS NewsHour / Domenico Montanaro, Rachel Wellford, and Simon Pathe] "The science is clear: The earth is round, the sky is blue, and #vaccineswork. Let's protect all our kids. #GrandmothersKnowBest" [Hillary Clinton] In general, support for vaccines is bipartisan. [Vox / Andrew Prokop] The science is very clear: vaccines don't cause autism. [Vox / German Lopez] 3. ISIS is still terrible A new video allegedly shows ISIS burning a captured Jordanian pilot alive. [Washington Post / Taylor Luck and William Booth] President Obama: "It's just one more indication of the viciousness and barbarity of this organization." [Huffington Post / Paige Lavender] ISIS uses these videos to try to build its brand of terrorism and to exert its power. [Vox / Amanda Taub] But some analysts are beginning to question whether ISIS's hostage tactics are even effective or just needlessly cruel. [New York Times / Rod Nordland] If you're unsure what ISIS is, check out our explainer. [Vox / Zack Beauchamp] 4. Misc. The Senate failed to pass a funding bill for the Department of Homeland Security — mostly due to disagreements over President Obama's executive actions on immigration. [Vox / Dara Lind] "To Kill a Mockingbird" author Harper Lee has a new book coming out. [Vox / Kelsey McKinney] A congressman's office looks like the set of "Downtown Abbey." [Washington Post / Ben Terris] Why cats love boxes: they're comforting — and allow a sneak attack. [Wired / Bryan Gardiner] These five men were scientific geniuses. They also thought magic was real. [Vox / Phil Edwards] 5. Verbatim "I thought that if all I had to do was chop my leg off, then let's get on with it. Let's do it." [Vox / Rebekah Gregory DiMartino] "King Abdullah of Jordan picked up the tab for a Christie family weekend at the end of the trip." [New York Times / Kate Zernike and Michael Barbaro] "Jennie and Kristian Aspelin have five sons  —  Lukas, who is six; Johan, who would be four but is dead; and the triplets, Peter, Rudy, and Tommy, who just turned one." [Medium / Elizabeth Weil] "At one point, [Pennsylvania Attorney General Kathleen] Kane went on national television to say that some of the emails contained pornographic images of children, a felony crime, a charge for which her office later admitted it had no evidence."
