Students across the country are expected to walk out of their classrooms Wednesday morning to protest gun violence. The National School Walkout is scheduled to begin at 10 a.m. in every time zone and last for 17 minutes -- a minute for each life lost in the Parkland school shooting.If you're a student who's thinking of taking part (or the parent of one), you probably have lots of questions: Can the school retaliate? Will it hurt your chances of college? Can you just stay home for the day?For help with answers, we turned to a couple of experts:Ben Wizner is the director of the ACLU's Speech, Privacy, and Technology Project and an adjunct professor at New York University School of Law. He's litigated numerous cases involving the intersection of civil liberties and national security. He's also the principal legal advisor to Edward Snowden.Christine V. Hamiel is an attorney at the von Briesen & Roper law firm in Milwaukee, Wisconsin. She chairs the firm's school law section and advises school districts on legal matters involving student issues, among other things. 1088

The Asian giant hornet first made waves this spring when it appeared in the United States. Discovered in Washington State, some dubbed it the murder hornet, but since then, entomologists have been feverishly trying to eradicate it."Quite a bit has happened. First, we had an initial planning with our AFS counterparts and also our counterparts in Canada who are having detections of their own. We formulated one or two different plans and put one or two of them into action," says Sven-Erik Spichiger, the Managing Entomologist at the Washington State Department of Agriculture.The Asian giant hornet is the world's largest hornet. It's more than two inches long, and queens can be even bigger. They feed on honey bees, attacking and killing tens of thousands of them at a time.Last November, beekeeper Ted McFall was blown away when he discovered one of his strongest hives had been attacked."Every time I go and check my hives, I kind of have a bad feeling when I start thinking about the Asian giant hornets that are somewhat establishing nests in the woods around me because I think to myself, 'Which one of these colonies is going to get it? Next time I come out here, am I going to show up and there's going to be bee heads everywhere and just bee carnage everywhere?' It's a very unsettling feeling," says McFall.The Asian giant hornet has been spotted and caught near McFall's property. Spichiger says the Washington State Department of Agriculture and the surrounding community have been hard at work setting traps."We have an excellent public survey going on with over 1,000 traps established by just members of the general public. This is very heartwarming to me because it means everyone is taking it very seriously and going above and beyond to help us look for new detections of this invasive pest," says Spichiger.Spichiger says so far, one has been discovered just over the Canadian border and three in Whatcom County in Washington State. Two of those discovered were queens, which is crucial since the Asian giant hornet hive can't survive without its queen. There have also been two cases where people were likely stung by an Asian giant hornet."She described being stung as having hot tacks driven into her flesh... What she described seeing in the yard earlier that day sounded like an Asian giant hornet. Again, it's an unconfirmed report, but we believe it happened," says Spichiger."Beekeepers have all types of bee equipment and protection against bees but this is totally useless against the Asian giant hornet. The Asian giant hornet can poke his stinger right through here. Even if I wore two of them," says McFall.As for whether Washington State agriculture officials feel they're closer to eradicating the Asian giant hornet, Spichiger says: "Eradication is going to be a long process. We will only know for sure if we’ve been successful if we have three years of all negative surveys and nobody turns any in. So from a realistic sense, no, I’m three years away."Still, the capture of the Asian giant hornets, including the two queens, is progress.McFall has 16 traps set up within a mile of his hives. He's on high alert, hoping none of his honey bees get attacked again."This is a [container] with orange juice and rice wine. They'll smell it and go through the hole. That hole is a little bit narrower than 3/4 inch and then they'll go in and not find their way out. They'll try and fly out and not be able to get out," says McFall.The traps are the same used by entomologists at the Washington State Department of Agriculture. Entomologists will be setting another 40 live traps near the most recent sighting. They're hoping to catch a live Asian giant hornet and tag it so they can track it to their nest. 3747

Stocks tumbled Friday as trade tensions between the United States and China heated up.The Dow closed down 572 points, a drop of 2.3%, after President Trump threatened to escalate a confrontation with China over trade. It fell as much as 767 points earlier in the day. The S&P 500 and the Nasdaq each declined more than 2%.Friday's losses wiped out gains for the week, and the Dow sank back into correction territory — 10% below its all-time closing high in January.Trump said late Thursday that he was considering tariffs on 0 billion more in Chinese exports, which would triple what the United States is already planning."The fear of a policy mistake on trade is increasing," said Art Hogan, chief market strategist at B. Riley FBR.All 30 companies on the Dow lost ground on Friday. Caterpillar, Boeing and Nike, giants with heavy exposure in China, were among the biggest losers in the index."The ratcheting up of trade tensions clearly carries risks. The tariff threats, even if only intended as bargaining tools, will be difficult to back down from if talks fail to deliver results," Capital Economics' Julian Evans-Pritchard wrote in a research note Friday.Anxiety returned to Wall Street after three days of gains. The VIX, a measure of market volatility, spiked 12%. CNNMoney's Fear and Greed index sank further into "extreme fear" territory.Wary investors had been holding out hope that the two sides will reach a deal before the proposed trade barriers go into effect.White House officials, including top economic adviser Larry Kudlow, have sought in recent days to soothe business leaders' fears of a trade war that would constrain economic growth.Earlier this week, the Trump administration announced plans for tariffs on billion worth of Chinese goods in retaliation for China's alleged theft of US intellectual property. Beijing fired back hours later by threatening tariffs on billion worth of US goods, including cars, planes and soybeans.The market had been interpreting Trump's proposed tariffs as negotiating tactics meant to extract concessions out of China rather than a rigid position. But Wall Street began to reassess that view as the administration sent conflicting signals throughout the day."We've gone from Larry Kudlow trying to calm the markets down to the administration saying, 'Hey, ignore the markets,'" Hogan said.In a radio interview Friday morning, Trump said, "I'm not saying there won't be a little pain, but the market has gone up 40%, 42%, so we might lose a little bit of it."Selling accelerated later in the day after Treasury Secretary Steve Mnuchin told CNBC, "There is the potential of a trade war."Investors had been operating under the assumption China and the United States were negotiating to avoid a trade conflict, but Mnuchin avoided questions about whether the two countries were actively talking."As no one came out to pull this back, there was a gradual realization that this was something that might be a little more serious," said Brad McMillan, chief investment officer for Commonwealth Financial Network.Analysts said the market also responded to comments from Federal Reserve Chair Jerome Powell.Powell said that the US economy was growing and a turbulent stock market would not change the Fed's course to gradually raise interest rates. The Fed is on track to raise rates three times this year, but it could speed up that process to cool down the economy."Markets are forced to confront the idea that rates are going up and the stock market is not going to derail that process," McMillan said.Stocks were mostly unaffected by the March jobs report, which showed that the US economy added 103,000 positions, down from a much bigger gain in February and well below what analysts were expecting.Wages grew 2.7% in March compared with a year earlier, in line with expectations. Investors were watching that number because it's a barometer of inflation. In February, an unexpected jump in wage growth set off inflation alarm bells and caused stocks to plunge.The combination of the hiring slowdowns and modest wage growth temporarily eased Wall Street's concerns that the economy was overheating.The yield on the 10-year US Treasury note, which has been steadily climbing as investors' inflation expectations rise, dipped to 2.78% after the jobs report."Investors breathed a sigh of relief," said Sam Stovall, chief investment strategist at CFRA Research. "Now we only have one issue to deal with, and that's trade."—CNNMoney's Paul R. La Monica contributed to this report.The-CNN-Wire 4564
