As President Donald Trump’s chances of re-election are sagging on Wednesday, the president declared himself a winner in the presidential election on Wednesday despite projections showing he is trailing Joe Biden in the Electoral College.As of Wednesday evening, Biden holds a 248-214 advantage in the Electoral College. Biden also holds an advantage in Michigan, Arizona, and Nevada. If Biden hangs on and wins those states, he’ll have a projected 270 Electoral College, which is exactly the number needed to win.Twitter has recently updated its policy regarding misinformation involving the election, and as of 2 p.m. ET Thursday, Trump had his Twitter account flagged eight times for misinformation. 709

Authorities say a seventh grader who died by suicide inside a northeast Ohio middle school bathroom last week planned to carry out an attack on the school.According to Jackson Township Police Chief Mark Brink, the Jackson Memorial Middle School student admired the Columbine shooters and had an eight-step plan to carry out an attack.The boy "intended to conduct a school shooting and harm others," Brink said. On Feb. 20, police responded to Jackson Memorial Middle School in Stark County after receiving a call about a student who had shot himself in the boy's bathroom.According to the medical examiner's office, the boy died from a self-inflicted gunshot wound to the head.Security cameras captured the 13-year-old on video coming out of the restroom with a .22 caliber semi-automatic rifle he had brought to school under his clothes. The boy went back inside the restroom and shot himself, police said.Investigators said it doesn't appear the boy shared his plan with anyone else, and he did not really have a presence on social media.Case of 13-year-old boy who shot himself inside Jackson Memorial Middle School has been ruled a suicide, according to the Summit County Medical Examiner. Boy passed away at Akron Children’s Hospital. @WEWS pic.twitter.com/JmlDIeLwbR— Bob Jones WEWS (@bobjonesTV) March 1, 2018 1354

AUSTIN, Texas. (KGTV) -- A series of explosions in Austin has terrified residents as hundreds of local and federal officials try and determine who is behind the incidents. The first explosion was set off on March 2 and killed 39-year-old Anthony Stephan House. Numerous other people have been killed or injured by the series of bombings including 17-year-old Draylen Mason, who was killed after a package bomb went off inside his home on March 12. Mason's mother was also injured in the explosion. A 75-year-old woman, 22-year-old man and a 23-year-old man were also all injured in the serial bombings. The six bombings left police in Austin warning residents to not take any chances, saying if it looks suspicious, don't approach it. The timeline below shows all six of the bombings federal officials believe are tied together:  887

  

Automakers are racing to develop driverless cars, putting increasingly complex technology on the road despite concerns from safety experts and the National Transportation Safety Board about a lack of regulations.Unlike rules for the design of a seatbelt or airbag, the federal guidelines for automated vehicle systems are voluntary. The U.S. Department of Transportation says keeping rules at a minimum will speed up the introduction of life-saving technology, a goal made all the more urgent as traffic deaths climbed again last year to 37,461, with 94 percent of those caused by human error.That lack of mandatory rules for self-driving cars has given automakers and technology companies the green light to police themselves, said Jackie Gillan, president of Advocates for Highway and Auto Safety. The group is calling for the government to issue mandatory safety standards for driverless cars.“Before we introduce this technology we need to have some assurance and accountability by the industry that this technology is not going to kill or injure consumers,” Gillan said.The National Transportation Safety Board makes recommendations after investigating major transportation incidents. The board recently called on DOT to issue new safety rules after its investigation of a May 2016 fatal crash of a Tesla Model S operating on autopilot near Williston, Fla. The Tesla slammed into a tractor-trailer, its cameras and automatic emergency braking system failing to spot the blank side of the truck against the white sky.It was the first known deadly wreck of a car driving with that level of automated sophistication. The NTSB said the driver relied too heavily on the car’s traffic-aware cruise control system and autosteering feature, but also blamed Tesla’s autopilot for allowing the driver to not interact with the car for prolonged periods of time.Investigators found the driver had his hands on the wheel for only 25 seconds during the 37 minutes the car was on autopilot. After the crash, Tesla updated its software that requires drivers touch the wheel every so often when the car is driving itself to ensure a human is paying attention to the road. Now if a driver repeatedly fails to touch the wheel, he or she will “strike out” and cause the car to slow down and stop in its lane with its hazard lights on, disabling autopilot for the remainder of the trip. 2378

  

As the reality of a coronavirus vaccine gets closer, it appears more Americans are willing to get it. A recent survey found nearly 60 percent of respondents said they would get a vaccine for the coronavirus.The poll conducted by Gallup in late October was done before Pfizer and Moderna shared the initial results of their clinical trials showing their separate vaccines were both more than 90 percent effective against the coronavirus.Roughly 58 percent of the nearly 3,000 respondents said “yes”, they would get a vaccine. During the last four months of polling Gallup has done on this question, the lowest “yes” response rate was 50 percent of respondents in mid-September.Since then, the FDA, other health experts and the drug makers themselves have sought to clarify the testing process and offer transparency about the approval process.The latest survey results still mean roughly 42 percent of those asked would not get a coronavirus vaccine.“Four in 10 remain unwilling to get a vaccine, indicating public health officials face an uphill climb in convincing a good share of the public to do so,” the Gallup report stated.A large increase in those who said “yes” in this latest survey came from respondents in the 45-to-64 years old group. In mid-September, there was only 36 percent of this group who would get a vaccine, in October, that number had increased to 49 percent.According to the survey results, it appears those who identify as Democrats remain the most willing to get a vaccine and increased the most in the latest survey, compared with those who identify as Republican remaining below 50 percent “yes” through the entire four months of Gallup’s polling.In the latest survey from late October, 69 percent of Democrats and 49 percent of Republicans would get the vaccine. In September, only 53 percent of Democrats said “yes.”As for reasons people gave for not wanting to take a coronavirus vaccine, Republicans were split among various answers; 26 percent were concerned about a rushed timeline, 20 percent don’t trust vaccines generally, 19 percent want to wait to confirm the vaccine is safe, and 22 percent said there were other reasons.Meanwhile, more than half of the Democrats who would not take a vaccine said it was because of concerns about a rushed timeline and they want to wait to confirm it is safe.Pfizer and Moderna have said tens of millions of doses of their vaccines could be available by the end of the year once they get the “go ahead” from the FDA. 2498
