Puerto Rico was hit with a massive power outage, the power authority said Thursday -- nearly seven months after Hurricane Maria destroyed much of the island's infrastructure and its electrical grid.The Puerto Rico Electric Power Authority, known as PREPA, said a tree fell on a major power line, knocking out service to 870,000 customers, about half of its clients. The utility tweeted an image it says was of the tree that fell across a power line near the southeast mountain town of Cayey.Major blackouts were reported from the northern coastal town of Manatí to Yabucoa, roughly 50 miles southeast.The blackout also includes the capital of San Juan, the most populated area of the island."We are devastated at this point," Cynthia García Coll, an educational psychologist who lives near San Juan, told CNN. "Every time this happens we go into PTSD mode."San Juan Mayor Carmen Yulín Cruz said it could take eight to 16 hours for electricity to be restored. 966

President-elect Joe Biden and his wife, Dr. Jill Biden, will receive an initial dose of Pfizer's COVID-19 vaccine in their home state of Delaware on Monday according to Reuters and PBS.Vice president-elect Kamala Harris will also receive the vaccine later this month, the outlets report.Biden said earlier this week that he would receive the vaccine "sooner rather than later," adding that he didn't want to "get ahead of the line, but I want to make sure we demonstrate to the American people that it is safe to take."It's not yet clear whether Biden would receive his vaccination in a live TV broadcast, as Vice President Mike Pence did on Friday morning.Three other former presidents — Barack Obama, George W. Bush and Bill Clinton — have all independently agreed to be vaccinated in a public setting to instill confidence in the vaccine's safety to the public.This story is breaking and will be updated. 915
