Today's edition of quick hits:
* The latest school shooting: "Two students were killed and more than a dozen people were wounded Tuesday when a 15-year-old armed with a handgun opened fire inside a Kentucky high school, the authorities said."
* Confirming what we suspected: "Special counsel Robert Mueller's investigators have interviewed Attorney General Jeff Sessions and former FBI Director James Comey as part of the ongoing federal probe into Russian meddling in the 2016 election, according to two people familiar with the investigation."
* On trade policy, how confident are we that Trump knows what he's doing? "President Donald Trump is signing a measure Tuesday imposing tariffs on imported solar-energy components and large washing machines in a bid to help U.S. manufacturers."
* Forgive the cliche, but being poor is expensive: "Bank of America Corp. has eliminated a free checking account popular with some lower-income customers, requiring them to keep more money at the bank to avoid a monthly fee."
* The suspect reportedly made references to "fake news" while threatening violence: "Authorities arrested a Michigan man last week after he allegedly called CNN several times, threatening to kill employees at the network's Atlanta, Georgia, headquarters, according to a federal affidavit."
* Someone should let Republicans know: "More than four in five Morgan Stanley analysts, across industries, said in a survey that the firms they track will use their tax gains to facilitate buybacks and dividends. Barely one in five said firms would pass even some of the tax gains on to workers."
* Congratulations to the senator and her family: "In the history of the nation, only 10 members of Congress have given birth while in office and Sen. Tammy Duckworth, D-Ill., is one of them. Soon Duckworth will be in a class by herself. Duckworth told me she is expecting her second child, another girl, in late April, a few weeks after she turns 50. The birth will make Duckworth the nation's first senator to have a baby while serving in the chamber."
