Today's edition of quick hits:
* Capitol Hill shooting: "Police locked down the US Capitol complex on Monday after a police officer was shot, NBC News has learned. 'Shooter has been caught,' the Capitol's sergeant at arms reported. 'One police officer shot, but not seriously.'"
* A devastating attack in Pakistan: "A suicide bomber set off a powerful blast close to a children's swing set in a public park on Sunday evening in the eastern city of Lahore, killing at least 69 people and wounding around 300, rescue workers and officials said."
* The investigation in Brussels continues: "Belgium on Monday released the sole suspect prosecutors had arrested directly in relation to the Brussels terror attacks."
* Um, can we talk a little more about this? "As a dragnet aimed at Islamic State operatives spiraled across Brussels and into at least five European countries on Friday, the authorities were also focusing on a narrower but increasingly alarming threat: the vulnerability of Belgium's nuclear installations."
* The whole idea of man-made earthquakes is still something I find extraordinary: "On Monday, the U.S. Geological Survey published for the first time an earthquake hazard map covering both natural and 'induced' quakes.... Some 7 million people live in places vulnerable to these induced tremors, the USGS concluded."
* A done deal in California: "A deal to raise California's minimum wage to $15 an hour by 2022 was reached Monday by Gov. Jerry Brown and state legislators, making the nation's largest state the first to lift base earnings to that level and propelling a campaign to lift the pay floor nationally."
* If only Donald Trump had some understanding of his own rhetoric: "Trade deficits are not inherently good or bad; they can be either, depending on circumstances. The trade deficit is not a scorecard."
* Idaho: "Beginning July 1, Idaho residents age 21 or older will be allowed to carry a concealed firearm without a permit inside city limits. Gov. C.L. 'Butch' Otter has signed Senate Bill 1389 into law, which will relax the state's gun policy and remove permitting requirements for concealed carry."
* If there were a competition to see who could come up with the least persuasive rhetoric related to the Republicans' Supreme Court blockade, clearly Sen. Orrin Hatch (R-Utah) would be a gold medalist. The poor guy just doesn't seem to feel any shame whatsoever.
* I'm not overly fond of air travel. This won't help: "An American Airlines pilot was arrested Saturday on the runway as shocked passengers looked on after he failed a breathalyzer test at the Detroit Metropolitan Airport." Note, the three words that jump out at me in that sentence were "on the runway."
