Two more members of President Donald Trump’s campaign working on his rally in Tulsa, Oklahoma have tested positive for the coronavirus.The president’s campaign put out a statement Monday that said the two staffers, part of the advance team for Saturday’s rally, tested positive before they boarded their flight out of Oklahoma.The two were then quarantined and the campaign began contact tracing protocols. These positive tests follow the news that six other staffers, including two Secret Service agents, tested positive in the hours before Saturday’s rally.The rally was believed to be the largest indoor event in the nation since the onset of the COVID-19 pandemic. The White House did not immediately plan any specific infection monitoring for the event. 766

US President Donald Trump has pointed to a massive caravan of migrants trekking north through Mexico as a major issue in the upcoming midterm elections.But when Election Day rolls around, on November 6, the caravan could still be somewhere in the middle of Mexico, given the group's current location, how fast it's been traveling and how long it's taken other groups of migrants to cross the country.On Tuesday, the caravan was in Huixtla, Mexico, about 50 miles from the Mexico-Guatemala border, where many of the caravan's members skirted authorities and crossed in rafts.It's still too soon to know exactly where along the vast US-Mexico border the bulk of this caravan will travel.The group only recently crossed into Mexico, and members are charting their movement daily.Organizers have told CNN they still don't know exactly which route they'll take. Much depends on the Mexican government and what routes the caravan is allowed to travel, whether its members are detained or held in certain areas and whether the group is provided with buses to speed their journey.There's a possibility some members of the caravan will split off and try to make their own way to the US-Mexico border, and that others will decide to stay in Mexico -- or return to their home countries. There's also a possibility Mexican authorities will detain members of the caravan at some point along their journey.The safest route would take them to Tijuana, across the US border from San Diego. A large caravan that crossed Mexico in the spring -- and also drew ire from President Trump -- took more than 30 days to reach Tijuana from Tapachula, Mexico -- a city this caravan departed on Monday.The closest border crossing to this caravan would be between Matamoros, Mexico, and Brownsville, Texas, about 1,111 miles away from the caravan's current location. But heading that way is considered a more dangerous route.To date, the caravan has traveled about 20 miles a day, largely on foot. If the caravan continues at that rate, reaching Tijuana could take months, and reaching Matamoros could take weeks. 2117

Vaping is being linked to an increased risk of Covid-19 among teenagers and young adults, according to a new study.Researchers at Stanford University School of Medicine looked at connections between youth vaping and Covid-19 cases in the U.S. They analyzed online surveys conducted in May by 4,351 people between the ages of 13 and 24.Among teens and young adults who took a coronavirus test, those who vaped were five to seven times more likely to test positive.“Teens and young adults need to know that if you use e-cigarettes, you are likely at immediate risk of COVID-19 because you are damaging your lungs,” said the study’s senior author, Bonnie Halpern-Felsher, PhD, professor of pediatrics.The participants were evenly divided between those who had used e-cigarettes and those who had never used nicotine products.Participants who admitted to using both cigarettes and e-cigarettes in the previous 30 days were almost five times as likely to have Covid-19 symptoms, including coughing, fever, tiredness and difficulty breathing, compared to those who never smoked or vaped.Young people who vaped or smoked, or both, were about two to nine times more likely to receive COVID-19 tests than nonusers.Among those surveyed who had taken a Covid-19 test, those who had used both e-cigarettes and cigarettes in the previous 30 days were 6.8 times more likely to test positive for the coronavirus.“This study tells us pretty clearly that youth who are using vapes or are dual-using [e-cigarettes and cigarettes] are at elevated risk, and it’s not just a small increase in risk; it’s a big one,” said the study’s lead author, postdoctoral scholar Shivani Mathur Gaiha, PhD.Researchers hope their study will be a warning about the dangers of vaping, and also prompt the Food and Drug Administration to consider tighter regulations on vaping products. 1856

U.S. energy consumption plummeted to its lowest level in more than 30 years this spring as the nation’s economy largely shut down because of the coronavirus, federal officials reported Wednesday.The drop was driven by less demand for coal that is burned for electricity and oil that’s refined into gasoline and jet fuel, the U.S. Energy Information Administration said.The declines were in line with lower energy usage around the globe as the pandemic seized up economies.Those trends are turning around as commercial activity resumes but the impact has already been profound — including energy companies filing for bankruptcy protection and a forecasted dip in annual U.S. and global greenhouse gas emissions.Overall U.S. energy consumption dropped 14 % during April compared to a year earlier, the energy administration said. That’s the lowest monthly level since 1989 and the largest decrease ever recorded in data that’s been collected since 1973.The largest drop previously seen was in December 2001, after the Sept. 11 attacks shocked the economy and a mild winter depressed electricity demand.Natural gas bucked the trend with a 15 percent increase in use during the April lockdown. More people at home meant more demand for natural gas as a heating fuel, while relatively few homes are heated with coal or oil, said Brett Marohl, who helped produce the energy administration findings.Petroleum consumption fell to 14.7 million barrels a day in April, down almost a third compared to the same period in 2019. Demand already has rebounded some after stay-at-home orders expired and large sectors of the economy started moving again.Led by people resuming some of their old driving habits, particularly in cities, petroleum consumption in June was back up to 17.6 million barrels a day, according to the American Petroleum Institute. But new drilling activity continued to be weak, declining in June for the seventh month in a row to 11 million barrels daily as stockpiles of oil and petroleum products remained near record levels.The spring drop in oil demand coincided with a market collapse triggered by a price dispute between Russia and Saudi Arabia.“While we are not out of the woods yet, we do appear to be headed in the right direction,” said Dean Foreman, the industry group’s chief economist.Coal companies are expected to have an even tougher time recovering from the pandemic, which hit as the coal sector remained on a fairly steady downward spiral since 2007 despite President Donald Trump’s attempts to prop it up.Coal consumption fell 27 percent in April compared to the same period in 2019, to 27 million tons. Most coal produced in the U.S. is used to generate electricity but many utilities have switched to cheaper natural gas and renewable sources like wind and solar.The energy administration projects overall consumption will increase for the rest of 2020 but remain below 2019 levels.___Follow Matthew Brown on twitter: @matthewbrownap 2972
