Andrew McCabe is describing his firing as part of President Donald Trump's "ongoing war" with the FBI and the special counsel investigation.Attorney General Jeff Sessions fired the former FBI deputy director Friday, two days before McCabe was set to retire, ending his two-decade career with the bureau."This attack on my credibility is one part of a larger effort not just to slander me personally, but to taint the FBI, law enforcement and intelligence professionals more generally," McCabe said in a statement after his firing."It is part of this administration's ongoing war on the FBI and the efforts of the special counsel investigation, which continue to this day. Their persistence in this campaign only highlights the importance of the Special Counsel's work," he added. 787

Amid all of the retail chaos and change of 2020, at least one thing remains the same: the biggest sale day of the year.Black Friday — the day after Thanksgiving — has a reputation as the best time of the year to buy just about anything.But even though Black Friday still exists in 2020, it won’t be the same experience as before. Our guide can help you get the best bargains this Nov. 27.Buy: TelevisionsLow-priced electronics deals are a given on Black Friday. That won’t change this year.Last year, Target sold a 65-inch TV in stores for only 9.99. Walmart, too, had a 65-inch TV for just 8. This Black Friday, you’re guaranteed to find discounts on TVs, as well as tablets and laptops.As for some stocking stuffers to go along with your new TV, you’ll find video games, CDs, DVDs and Blu-rays deeply discounted from their original prices. In 2019, Walmart had over 50 movie titles for .96 apiece.Skip: ToysHistorically, it’s best to wait until closer to Christmas to purchase dolls, action figures, play sets and other toys. You run the risk that certain items will sell out, but you may also be able to find bigger savings on what’s left.In past years, select toys have been on sale for as much as 50% off in the final days before Christmas.Buy: Apple productsThere’s a specific electronic brand that’s popular on Black Friday: Apple. Major retail stores such as Best Buy, Target and Walmart discount Apple products each year, and previous-generation models usually see dramatic deals. These offers may include price cuts, free gift cards with purchase (up to 0 with a qualifying phone purchase on an installment plan), or a combination of both.Target devoted an entire page of its 2019 Black Friday ad to Apple. The Apple Watch Series 3 (GPS) started at 9.99 (regularly 9.99), and select App Store and iTunes gift cards were buy one, get one 30% off.Apple discounts likely won’t disappear this Black Friday. In fact, Apple items have already been on sale in pre-Black Friday sales. Keep an eye out for deals on MacBooks, iMacs, iPhones, iPads, Apple Watches and Apple TVs.Skip: BeddingYou’ve got the entertainment center covered, but hesitate before stocking up on supplies to refresh the look of your bedroom this Black Friday.Every January, retailers such as Overstock, Pottery Barn and Sears host “white sales.” During these seasonal promotions, discounts on bedding, pillows, towels and linens can hit up to 70%. Expect these to come around after Jan. 1.Buy: Gaming systemsBlack Friday is big for gamers. This year, look for savings on video game systems from retailers such as Best Buy, Walmart and GameStop. Expect deals on products from Xbox, PlayStation and Nintendo.You’ll also find particularly great offers on gaming bundles. These include the game console plus a combination of accessories or games.Skip: Winter clothingWinter clothing generally isn’t the best value on Black Friday. Retailers frequently offer big clearance sales on jackets when winter gives way to spring.But if you need something to keep you warm before then, you’ll be able to find some bargains this Black Friday. Year after year, department stores like to offer doorbuster deals on women’s boots with select pairs for just .99 each.If you miss Black Friday, don’t worry. Department stores and clothing retailers have been rolling out new sales almost daily.Buy: Christmas decorBlowout post-Christmas clearance sales happen every year on Dec. 26 as shoppers make their way to the store to return gifts. Christmas decorations, wrapping paper, tinsel and other seasonal trimmings reach super low prices (for obvious reasons). Prices also drop in the final weeks before Christmas.For those reasons, Christmas decorations used to be on our list of items to skip on Black Friday. But this year, it’s less likely you’ll be at the mall shortly before Christmas. And waiting to order online could spell shipping delays.So if you need decorations, consider scooping up deals on artificial trees and rolls of wrapping paper from home and craft stores on Black Friday. That way you’ll have your essentials in time for Christmas.Skip: Outdoor itemsOutdoor products, grills and patio furniture were already deeply discounted immediately after summer ended.If you didn’t pick up these products at the close of this summer, wait until Memorial Day and Labor Day sales roll around next year. Another viable option is the Spring Black Friday Sale that home improvement store Lowe’s usually holds each year.Buy: AppliancesBlack Friday brings big savings on washers, dryers, refrigerators and other kitchen appliances. Retailers typically mark down home appliances by 40%. Look for similar deep discounts again this year.You’ll find smaller appliances such as coffee makers, mixers, blenders or vacuum cleaners on sale, too. Expect deals from department stores such as Kohl’s, Macy’s and JCPenney.Shop: OnlineFor the ultimate combination of convenience, safety and savings, spring for online shopping. With so many stores closed on Thanksgiving, big-box retailers are bringing their doorbusters online this Thanksgiving and Black Friday.Online shoppers will usually enjoy free shipping. Or, you can choose to make your purchases online and pick them up at the store.More From NerdWalletHow to Get the Best Lowe’s Black Friday 2020 Deals13 Ways to Leave Scammers Empty-Handed This Holiday SeasonHow to Shop Black Friday Deals OnlineCourtney Jespersen is a writer at NerdWallet.

Ananya Vinay, the 2017 Scripps National Spelling Bee champion, has had quite a year.It started with confetti cannons on stage after she spelled "marocain" correctly. Then she made the rounds: talk shows like Jimmy Kimmel Live and other media appearances.She rode in a limo to the Golden State Warriors' final basketball game of last season, and got to see the trophy presentation when her team won the championship."It was really exciting," she said.She also toured the Google campus, got a rally at her school and had a day named in her honor by the governor of California. It was all a big surprise, she said.And she's picked up other hobbies, too: she made it to the National Science Bowl, the state science fair and competed in Mathcounts.She also wants to write more and join the forensics team. And she's started a website and tutors some spellers.A lot of it comes from her Bee experience."It really gives you a lot of confidence," Ananya said. "It gives you a lot of knowledge about the world."Ananya carried the trophy in to the opening ceremony Monday night and kicked off the Bee."I'm really glad to be back; I have a lot of friends here," she said. "I'm hoping for the best for every competitor." 1216

  

As health officials around the world tack COVID-19 infection rates, two universities in the U.S. have partnered with Facebook to try to predict infections with real-time survey data.Dr. Alex Reinhart, an assistant teaching professor of statistics and data science at Carnegie Mellon University and a member of the Delphi Group, says that as health officials were struggling with testing capacity in the spring, they realized they might be able to predict infections by analyzing social media."They realized that if we could know when people are experiencing symptoms, they probably experience symptoms a few days before seeing a doctor. That's probably a few days before they get test results back and so that could potentially be an early indicator," Reinhart said.The Delphi Group reached out to Facebook, which agreed to help them survey its users."Every day Facebook takes a random sample of their active users that day in the United States and internationally and invites them through a little blurb at the top of their newsfeed that says, 'you can help coronavirus research' if you take this survey, which is voluntary," Reinhart said.Once Facebook users click on the survey button, it takes them to Carnegie Mellon's page for the survey. The University of Maryland also jumped on board with the project and conducted the survey for all international Facebook users.Facebook does not receive any survey data and only refers to the interested participants to the survey links. So far, more than 30 million people have taken the survey.Dr. Frauke Kreuter, who is working with the University of Maryland in Germany on the international side, says she's not aware of another global survey on COVID-19."There are two factors globally, I would say. One, is that many countries do not have good reporting systems and so they rely even more on alternative data sources. And the other one is, you want to compare yourself to other countries, but for that you need to have kind of the same measure in each country," Kreuter said. "And that's what we're lacking with a lot of measures right now because each country does there reporting slightly different."So far, Carnegie Mellon and the University of Maryland have been able to develop heat maps showing coronavirus symptoms across the country and world. Reinhart says they've been on par with COVID-19 infection rates being reported from health officials and says the survey has helped them identify patterns when it comes to mask-wearing and infection rates."In early September, we started asking questions about mask usage and we soon found that there is a striking difference in mask usage across the country," Reinhart said. "At the time, places that had lower mask usage seemed to be having a worse time in the pandemic."Reinhart says the survey results are helping them learn more about the effects of mask mandates. Researchers are hoping to continue the survey as the pandemic evolves — for example, they hope to begin gauging users on vaccine usage and skepticism in the coming months.The data is available for anyone to view and use."It's different from what you can get from cell phone mobility data that we see people use because we get to directly ask people what they're thinking, how they're feeling, what they're experiencing," Rinehart said. "We'd like as many people as possible to discover this data and use it for their own important research questions." 3430
