Federal Communications Commission Chairman Ajit Pai, a Republican, says he is leaving the telecommunications regulator on Inauguration Day. President-elect Joe Biden will choose a new Democratic head for the agency. A new administration typically picks a new chairman. The FCC typically has three commissioners of the majority party and two in the minority party. It currently has two Democratic commissioners, Jessica Rosenworcel and Geoffrey Starks, one of whom Biden could choose to elevate to chairman or choose someone from outside the agency.Pai and another Republican commissioner, Michael O’Rielly, are leaving the agency. O’Rielly is leaving because the White House pulled his nomination after he said he wasn’t sure the agency had authority on Section 230. Congress is weighing the nomination of another Republican, Nathan Simington.Pai has presided over a contentious FCC. He undid net neutrality rules that barred internet service providers like Comcast and AT&T from favoring some types of online traffic over others in 2017 and championed other deregulatory efforts. The incoming FCC is likely to try to reinstate net neutrality rules and focus on getting internet service to more Americans.They will likely not act on a recent directive from the Trump administration to look at Section 230 in an effort to regulate social media companies like Facebook and Twitter. Section 230 shields internet companies from lawsuits about posts by users. The Trump administration has gone after the law, alleging with no evidence that social networks censor conservatives. Pai had recently said the FCC could move forward making rules around Trump's directive about looking at Section 230. 1702

Every year, millions of kids across the country look forward to dressing up, knocking on doors and celebrating Halloween with lots of candy. But this year, the pandemic is likely changing some of those celebrations.So, is it still possible to celebrate Halloween this year?"That's a great question. I'm not just a doctor, but I'm also a parent to three young boys who are of trick-or-treating age. So, it's certainly a question that gets asked a lot in my wife's pediatric practice, as well,” said Dr. Kenny Banh, an emergency room physician and assistant dean of undergraduate medical education at UCSF-Fresno. “I have to say, I don't want to give a blanket answer, because it really depends on where you are and what the numbers are."Dr. Banh says there are ways to trick-or-treat this Halloween, but you first have to look at your local city and county ordinances."There’s simple things of just maintaining the guidelines. How do you do a mask? There are ways to incorporate masks in a costume and make sure we make or get costumes with masks integrated into them and trying to maintain social distancing,” suggested Dr. Banh. “The good thing about candy is years ago we moved away from homemade candies. Almost all candy is packaged already, so that’s helpful.”Still, limiting the number of people who touch the candy is a good idea along with wiping down the packaging.If you're wanting to pass out candy this Halloween, it's best to do it with a mask on and try to limit the number of trick or treaters handling the candy."Some recommendations are prepackaged candy, give little candy gift bags people can grab as they get by, instead of having kids reach in with their hands and grabbing a bunch of stuff, or you passing out with gloves or getting tongs and just dropping them into or getting a scooper letting kids drop it in," said Dr. Banh.Dr. Banh's biggest concern is with Halloween parties."Having Halloween parties and getting kids from the neighbors or friends all together, that’s really different than you as a nuclear group going as a family going out trick-or-treating and doing it safely,” said Dr. Banh. “Trying to understand that we’re finally making some ground in many states and we can easily go backwards. Labor Day, Halloween all these things sort of letting our guard down on those aspects.”Doctors say it's important to stay vigilant when it comes to protecting yourself from coronavirus so that the only frightening things we're encountering this Halloween are scary costumes and decorations. 2530

Federal prosecutors Friday requested that Donald Trump's former personal attorney Michael Cohen receive "a substantial term of imprisonment" for various finance-related crimes.In separate filings, prosecutors from special counsel Robert Mueller's office and the Southern District of New York outlined their cases for Cohen's future.In August, Cohen pleaded guilty to eight federal crimes after being charged by Manhattan federal prosecutors. Those included tax fraud, making false statements to a bank and campaign-finance violations tied to his work for Trump, including payments Cohen made or helped orchestrate that were designed to silence women who claimed affairs with the then-presidential candidate. Trump has denied those claims."After cheating the IRS for years, lying to banks and to Congress, and seeking to criminally influence the Presidential election, Cohen's decision to plead guilty -- rather than seek a pardon for his manifold crimes -- does not make him a hero," prosecutors for the southern district wrote.In its filing, Mueller's office says that Cohen took "significant steps" to help the investigation has accepted responsibility for his crimes. It argues any sentence he serves run concurrently. 1229

Fans of Nutella are going absolutely nuts after the brand changed its recipe.Nutella said in a post on its German Facebook page on Tuesday that it was "fine tuning" its recipe. It said the addition of more powdered milk increased the spread's sugar content.The brand's U.S. Twitter page also confirmed the recipe had changed. The news was met with howls of rage on the internet, where loyal customers professed their love for the old recipe."OMG!! They are changing the recipe of #Nutella!!!," wrote one Twitter user. "NOOOOOOOO HOW DARE THEY!! Leave the sugar & coco alone!!!"The recipe change was first publicized by the Hamburg Consumer Protection Center, which said last week that the tweak had made the chocolate spread's color lighter.The group said that, according to the ingredient list printed on Nutella packaging, the proportion of skimmed milk powder had increased to 8.7% from 7.5%."Cocoa has slipped back in the list of ingredients," it said. "As the color of the new Nutella is lighter, we assume that more milk powder was added at the expense of cocoa."Ferrero, the Italian company that makes Nutella, declined repeated requests from CNN for more information about the recipe change.But its fans appear to have already made up their minds."Nutella is sweet enough," wrote another Twitter user. "Why on earth change something that no one has a problem with?"Nutella was created after World War II, when a cocoa shortage in Italy required pastry makers to get creative. One chef, Pietro Ferrero, created the spread using hazelnuts, sugar and a bit of cocoa.Ferrero is not the only chocolate maker to face a public backlash over changes to a beloved product.British Toblerone fans reacted with horror last year after discovering that the distance between the triangular chunks in the chocolate bar had expanded overnight.Mondelez International, which produces the airport shopping staple, said they were forced to shrink the bars from 170 grams to 150 grams because of rising ingredient costs.It may not be the last recipe change for Nutella.Ferrero has been working in recent years to gain more control over the production and supply of hazelnuts -- a critical ingredient in Nutella and Ferrero Rocher treats.There are limited places where the nuts can be grown, with the majority coming from Turkey.Tom Molnar, a plant biologist and hazelnut expert at Rutgers University, warned that any disruption to hazelnut supplies would be deeply problematic."If there's a crop failure in Turkey, they're not going to be able to sustain [production levels]," he said.  2592
