The Trump Administration wants to change the definition of a showerhead to let more water flow, addressing a pet peeve of the president who complains he isn’t getting wet enough.Publicly talking about the need to keep his hair “perfect,” President Donald Trump has made increasing water flow and dialing back long held appliance conservation standards — from light bulbs to toilets to dishwashers — a personal issue.But consumer and conservation groups said the Department of Energy’s proposed loosening of a 28-year-old energy law that includes appliance standards is silly, unnecessary and wasteful, especially as the West bakes through a historic two-decade-long megadrought.Since 1992, federal law has dictated that new showerheads shouldn’t pour more than 2.5 gallons of water per minute (9.5 liters). As newer shower fixtures came out with multiple nozzles, the Obama administration defined the showerhead restrictions to apply to what comes out in total. So if there are four nozzles, no more than 2.5 gallons total should come out between all four.The new proposal Wednesday would allow each nozzle to spray as much as 2.5 gallons, not just the overall showerhead.With four or five or more nozzles, “you could have 10, 15 gallons per minute powering out of the showerhead, literally probably washing you out of the bathroom,” said Andrew deLaski, executive director of the energy conservation group Appliance Standards Awareness Project.On the White House South Lawn in July, Trump made the issue personal:“So showerheads — you take a shower, the water doesn’t come out. You want to wash your hands, the water doesn’t come out. So what do you do? You just stand there longer or you take a shower longer? Because my hair — I don’t know about you, but it has to be perfect. Perfect.”DeLaski and officials at Consumer Reports said there’s been no public outcry or need for change. The Department of Energy’s own database of 12,499 showerheads showed 74% of them use two gallons or less water per minute, which is 20% less than the federal standard.“Frankly it’s silly,” deLaski said. “The country faces serious problems. We’ve got a pandemic, serious long-term drought throughout much of the West. We’ve got global climate change. Showerheads aren’t one of our problems.”Energy Department spokeswoman Shaylyn Hynes said the 2013 Obama definition of showerhead clashes with what Congress intended and the standards of the American Society of Mechanical Engineers.If the rule is adopted, Hynes said it would be “allowing Americans — not Washington bureaucrats — to choose what kind of showerheads they have in their homes.”Officials at the industry group Plumbing Manufacturers International did not respond to a request for comment.Appliance and plumbing energy and water conservation standards save consumers about 0 a year on energy bills, deLaski said.If people are having trouble getting water flowing in their shower, they should check their home’s water pressure and can replace a faulty showerhead for not much money, deLaski said.A 2016 test of showerheads by Consumer Reports found that the best rated showerheads — including a model — provided a pleasing amount of water flow and met federal standards, according to David Friedman, a Consumer Reports vice president and former acting assistant energy secretary.DeLaski said he has had a hard time understanding the president’s shower concerns.“If the president needs help finding a good shower, we can point him to some great consumer websites that help you identify a good showerhead that provides a dense soak and a good shower,” deLaski said. 3624

The Russian government denied Monday that it had interfered in the 2016 US election campaign in the Kremlin's first remarks since 13 Russian nationals were indicted Friday on charges of conspiring to defraud the US.Answering a question from CNN on a weekly telephone news conference, the spokesman for Russian President Vladimir Putin, Dmitry Peskov, said the indictments provided "no substantial evidence" of Russian meddling, and that there were "no indications that the Russian state could have been involved.""We didn't see any substantial evidence of someone interfering in the domestic affairs," Peskov added. He said the US indictment "mentions Russian citizens, but we heard the accusations against the Russian state -- that the Russian state, the Kremlin and the Russian government were involved."  820

The showdown over mail-in ballots is expected to heat up this week.Democrats are calling back Congress to vote on legislation to prevent the U.S. Postal Service from changing any of its operations. A House committee also called an emergency hearing for next week to address mail delays and concerns the White House is interfering.The USPS is removing hundreds of mail processing machines across the country and has warned 46 states that it may not be able to process all mail-in ballots in time to be counted for the election.“Are we going to force people to have to choose between their fundamental right to vote and their health?” asked Shaundra Scott with the South Carolina Democratic Party. “The American voters are going to be very frustrated that we may not know who the winner is until frankly December.”Political experts agree the presidential race, pandemic and mail-in voting will all lead to massive increases in voter turnout and probably a lot of contested results.Some states have streamlined mail-in and absentee voting for years. However, other states are rushing to change their voting process because of the pandemic.“When things like that happen, it doesn't inspire confidence. It leads to the fear that people who shouldn't be voting may potentially be voting or people that should vote are not going to get ballots because of a snafu,” said Matt Klink, a GOP strategist with Klink Campaigns.For example, New York changed the rules to make it easier to vote by mail ahead of the primary, and it provided pre-paid envelopes. But those envelopes were not postmarked, or they were returned late. And there were other issues like ballots that weren't signed. That led to one out of four mail-in ballots being disqualified.But voting by mail could close the gap on inequities.“Yes, there are rules and regulations that say your employer should give you two hours to be able to vote but if you’re working hourly and you’re working on a job that is shift based, even though voting is extremely important, taking away that two hours of pay from someone and them having to make that decision is huge,” said Scott.Some expert say Republicans fear mail-in ballots would capture new Democratic voters, but seniors also benefit from absentee and mail-in voting. They often skew red, according to the Brookings Institute.A major study of California, Utah, and Washington state's elections between 1996 and 2018 found there was no partisan advantage to voting by mail. 2482

The timelines on your Instagram accounts have probably been flooded recently with women posting black-and-white pictures of themselves.The premise of the viral trend comes as a way for women to support each other with the accompaniment of the hashtag #ChallengeAccepted in their caption.The origins of the first picture used in the trend were traced by Taylor Lorenz of The New York Times. Lorenz found that a journalist in Brazil posted the very first picture in the challenge.There had been reports that the challenge first began in order to bring awareness about femicide in Turkey, but Lorenz spoke to Instagram and tweeted that the hashtag in Turkey and the United States were unrelated. 700
