Welcome to Vox Sentences, our news bulletin breaking down the day's biggest stories.

1. Republican states against Obamacare

• Arizona passed a bizarre law that effectively bans the state from setting up its own health insurance exchange through Obamacare.

• The law is very clearly aimed as a response to an upcoming Supreme Court decision that could kill the federally run insurance marketplaces Arizona and 33 other states currently use.

• About 205,000 Arizonans get insurance through the federal marketplace; if the Supreme Court destroys the federal exchange and the state is banned from starting another one, those Arizonans will presumably lose their health insurance.

• The looming Supreme Court decision in King v. Burwell is over whether just a few words in Obamacare allow the federal government to set up health exchanges for states that don't set up their own.

• Ezra Klein's take: "The anti-Obamacare movement is making red states sicker and poorer."

• "The online media industry makes real money. It's now possible to find a career in this industry, rather than just a fleeting job. An organized work force is part of growing up."

  [Gawker / Hamilton Nolan]

• This is a big deal: Gawker would be the highest-profile online media venture to unionize.

  [Talking Points Memo / Michelle Chen]

• Gawker CEO Nick Denton said he's "intensely relaxed" about his writers' union drive.

• Slack is just a year old — and it already has more than 750,000 daily active users.

• Vox's Timothy Lee argues there's nothing crazy about Slack's $2.8 billion valuation.

• But the popularity has led to some problems: in February, Slack got hacked.

• Journalists, including those at Vox, have made a lot of use of Slack — in large part to avoid the tedium and clunkiness of email.

  [NiemanLab / Joseph Lichterman]

• Slack users spend nearly 10 hours a day on the app.

4. Misc.

• In a bit of a surprise, Republican presidential contender Jeb Bush called on Republicans in the Senate to confirm Loretta Lynch for attorney general; her nomination has been stalled for months.

  [Politico / Nick Gass]

• A new bill would ban former members of Congress from lobbying for life.

  [Vox / Andrew Prokop]

• The parents of an 8-year-old killed in the 2013 Boston Marathon bombing asked federal prosecutors to stop pursuing the death penalty for convicted bomber Dzhokhar Tsarnaev, if it would bring the trial to a speedier conclusion.

  [Vox / German Lopez]

• Tibetan mastiffs used to be huge in China — but the fad has come and gone.

  [New York Times / Andrew Jacobs]

• The Batman vs. Superman: Dawn of Justice trailer leaked — and it's not very good.

  [Vox / Alex Abad-Santos]

5. Verbatim

• "It's like my child, only it doesn't steal the car at 3 o'clock in the morning and come home stoned."

  [Rick Springfield to Vox / Kelsey McKinney]

• "What has been so deliriously fun about the first two seasons of Orphan Black isn't the fiction of the science; it's the fact of the women. But — spoiler alert — nothing good lasts."

  [New Yorker / Jill Lepore]

• "On one level, the mass attention paid to Clinton's trip to Chipotle is just a huge waste of everyone's time."

  [Vox / Matthew Yglesias]

• "It was a situation that most politicians would find utterly uncomfortable: caught in a freak snowstorm alone on the road with a journalist. But [Sen. Lindsey] Graham seemed to be enjoying himself."
