5 things to know for Sept. 9: Presidential debate, Wildfires, Kentucky shootings, Pope Francis, Apple ‘glow time’

CNN’s 5 Things brings you the news you need to know every morning.

The NFL season just got underway and already the Super Bowl is in the spotlight — just not the game itself. Pulitzer Prize-winning rapper Kendrick Lamar announced Sunday that he will be the headlining act for the Super Bowl LIX halftime show. Here’s what else you need to know to Get Up to Speed and On with Your Day. As Vice President Kamala Harris and former President Donald Trump get ready for their first — and potentially only — presidential debate, Trump over the weekend threatened prosecution and “long term prison sentences” for election officials and political operatives, who he suggested could cheat in the 2024 election, if he again wins the presidency in November. Trump’s threats of prosecution — part of his repeated, baseless efforts to cast doubt on the integrity of the 2024 election — come as early voting will soon be underway in a number of states. The debate on Tuesday at the National Constitution Center in Philadelphia will be the first face-to-face encounter between Harris and Trump, who are locked in a tight race. Raging wildfires in California and Nevada have led to mandatory evacuations of thousands of homes as forecasters warn of record heat in the West for the next few days. In California, the Line Fire has consumed more than 20,000 acres after igniting at the base of the San Bernardino Mountains on Thursday. The blaze has more than quadrupled in size since Saturday morning and more than 1,800 fire personnel are battling the wildfire, which was zero percent contained as of Sunday evening, according to Cal Fire. And in Nevada, the Davis Fire — a dangerous, wind-driven blaze south of Reno — has burned about 6,500 acres and remains zero percent contained as of late Sunday. Classes have been canceled in schools across parts of central Kentucky today and residents have been urged to remain on high alert as the deep-woods search for a man suspected of opening fire along I-75 enters its third day. Joseph Couch, 32, has evaded capture since Saturday afternoon, when authorities say he fired an AR-15 from a cliff ledge on the side of the interstate about nine miles north of London, Kentucky, striking 12 cars and wounding five people. Though his motive is still unknown, the attack appeared to be a “random act” of violence, Laurel County Sheriff’s Deputy Gilbert Acciardo said, according to The Associated Press. Pope Francis arrived in the tiny Southeast Asian nation of East Timor earlier today for the penultimate stop on a marathon trip through Asia and the South Pacific for the 87-year-old pontiff. East Timor is one of the world’s youngest countries and has deep ties to the Catholic Church, which was influential in its fight for independence from Indonesia. The country of just 1.3 million people is the second-most Catholic country in the world, with 97% of the population identifying as Catholic — the highest share outside of the Vatican. But the issue of clerical sexual abuse is also hanging over this leg of the pope’s visit as revelations of mistreatment concerning high-profile East Timor clergy have emerged in recent years. Two years ago, the Vatican acknowledged that it had secretly disciplined East Timor bishop and Nobel Peace Prize winner Carlos Ximenes Belo after he was accused of sexually abusing boys decades before.
