Today's edition of quick hits:
* Problems persist in Greece: "Political deadlock in Greece on Monday stoked a renewed sense of crisis about the fate of the European economy as new data confirmed a downturn in one of the world's major trading blocks."
* Are sanctions taking a toll on Iran? Yep.
* Gay marriage is not yet legal in Rhode Island, but Gov. Linc Chafee (I) issued an executive order today, recognizing same-sex marriages from other states.
* Jeffrey Toobin has a fascinating piece on Supreme Court Chief Justice John Roberts orchestrating the Citizens United decision.

* Given Edward Klein's background, it's going to be difficult to take his new attack book against President Obama seriously.
* Though Republicans no longer seem sure what to say about marriage equality, Sen. Rand Paul (R-Ky.) told an Iowa audience about the president over the weekend, "Call me cynical, but I wasn't sure his views on marriage could get any gayer."
* And speaking of Obama, the president delivered quite a commencement address at New York's Barnard College earlier today. It's about a half-hour long, but it's worth watching.
