Today's edition of quick hits:
* He's the first, but probably not the last: "Iceland Prime Minister Sigmundur David Gunnlaugsson will step down, the deputy head of his party said on Tuesday, after leaked files showed the premier's wife owned an offshore firm with big claims on Iceland's collapsed banks."
* A story we're watching: "The U.S. Supreme Court on Tuesday denied a request from a lawyer who once represented a woman known as the 'DC Madam' to release records from her famous escort service."
* The White House targets inversions: "The Treasury Department on Monday took aim at U.S. companies moving their headquarters overseas to lower their tax bills, issuing aggressive new rules intended to make such moves less profitable and throwing a potential wrench into Pfizer's recent $160 billion proposed deal to combine with Allergen and become an Irish company."
* Iran: "The U.S. Navy has confiscated a cache of weapons that it believes was being transported from Iran to Houthi rebels in Yemen, marking at least the third time in two months that such a shipment was stopped, Navy officials said."
* NATO: "President Obama and NATO Secretary General Jens Stoltenberg struck back Monday at Donald Trump's charge that the security alliance is 'obsolete,' too expensive and relatively useless in dealing with today's terrorism threats."
* Related note: "President Obama on Tuesday blasted Republican presidential front-runner Donald Trump for his plan to bar immigrants in the U.S. from sending money back home to force Mexico to pay for a new border wall. 'Oh, no. It's Trump,' a smiling Obama said when he was asked about the 2016 candidate's latest comments."
* And in order to avoid an unfortunate acronym problem, the Antonin Scalia School of Law at George Mason University will officially be referred to as the Antonin Scalia Law School at George Mason University. Go ahead and take a moment to read that first one again, with the resulting abbreviation in mind.
