VISTA, Calif. (KGTV) -- The Vista Unified School District announced Tuesday that its secondary schools would be pivoting back to virtual learning until the end of winter break.The decision only applies to district middle and high schools; students will have to finish the next three weeks of instruction virtually.Vista's elementary schools will continue with in-person learning.According to the latest community update on the district's website, the reason for the pause in in-person learning is based on the recent increase in the spread of COVID-19 "globally, nationally, regionally and locally."It goes on to say, "While Vista Unified has seen no evidence of the virus spreading within the school environment after 26 days of instruction in the Vista Classic learning model, the impact of the virus within our community is causing staffing challenges for teachers, instructional assistants, custodians, and other employees."The school board has a meeting scheduled for Dec. 15 to revisit the situation and discuss possible adjustments for the second half of the school year. 1086

WASHINGTON (AP) — President Donald Trump and his allies are taking what appear to be increasingly frantic steps to subvert the results of the 2020 election, according to law scholars, including summoning state legislators to the White House as part of a longshot bid to overturn Joe Biden’s victory. Trump also has personally called local election officials in Michigan who are trying to rescind their certification votes in Michigan. His legal team has suggested that a judge order Pennsylvania to set aside the popular vote there. And his allies are pressuring county officials in Arizona to delay certifying vote tallies. During a press conference Thursday, the president's personal attorney, Rudy Giuliani, who is working on the campaign's lawsuits, made accusations of voter fraud in a handful of states, and seemed to suggest officials in several big cities were working together. "It’s not a singular voter fraud in any one state. There is a pattern in several states," Giuliani said. "To any experienced prosecutor, it would suggest that there was a plan." However, he did not give any evidence or further details about what led him to believe there was a "plan," other than baseless statements that the cities had "a history of corruption."“It’s very concerning that some Republicans apparently can’t fathom the possibility that they legitimately lost this election,” said Joshua Douglas, a law professor at the University of Kentucky who researches and teaches election law.“We depend on democratic norms, including that the losers graciously accept defeat,” he said. “That seems to be breaking down.”Election law experts see this as the last, dying gasp of the Trump campaign and say there is no question Biden will walk into the Oval Office come January. 1774

WASHINGTON (AP) — Pfizer and BioNTech will supply the U.S. with an additional 100 million doses of the COVID-19 vaccine under a new agreement.The drugmakers said Wednesday that they expect to deliver all the doses by July 31. Pfizer already has a contract to supply the government with 100 million doses of its vaccine.Watch officials with Operation Warp Speed discuss vaccine distribution:Pfizer’s vaccine was the first to gain approval from the Food and Drug Administration and initial shipments went to states last week.It has now been joined by a vaccine from Moderna, which was developed in closer cooperation with scientists from the National Institutes of Health.A law dating back to the Korean War gives the government authority to direct private companies to produce critical goods in times of national emergency. Called the Defense Production Act, it’s expected to be invoked to help Pfizer secure some raw materials needed for its vaccine.Pfizer already has a contract to supply the government with 100 million doses of its vaccine under Operation Warp Speed, but government officials have said it’s more of an arms-length relationship with the company and they don’t have as much visibility into its operations. 1231

Virgin Galactic is preparing to land among the stars.On Wednesday, Virgin Galactic said they were working on its final preparations at its base in New Mexico as the VSS Unity is scheduled to launch into space from Spaceport America sometime in the fall.The company said the ship would be crewed by two pilots and several research payloads in the cabin.Virgin Galactic says its top priority is safety, so they want to make sure the pilots are prepared for the task at hand.To do just that, they will be using VMS Eve as an in-flight simulator. The pilots will use Eve to practice the identical approach and landing pattern since it's similar to Unity's, Chief Pilot Dave Mackay stated."The cockpit structure of Eve is almost identical to that of Unity: the same pilot seats and windows, as well as very similar flight controls and instruments," Mackay said in the press release.The company will go through a full, planned rehearsal before the VSS Unity takes flight. 973

WASHINGTON (AP) — Columbine. Newtown. And now, Parkland.A grim fellowship of parents, teachers and students affected by school shootings over the past two decades was sitting down with President Donald Trump on Wednesday as the White House sought to show resolve against gun violence amid questions about the president's commitment to action.A strong supporter of gun rights, Trump has nonetheless indicated in recent days that he is willing to consider ideas not in keeping with National Rifle Association orthodoxy, included age restrictions for buying assault-type weapons.RELATED: Florida massacre survivors chant 'vote them out' as other students walk out in solidarityThe president is facing growing calls for action on gun control after the mass shooting that took 17 lives at Marjory Stoneman Douglas High School in South Florida.Still, while Trump has said he wants to listen and has offered support for some limited gun-control measures, gun owners are a key part of his base.Throughout the day Wednesday, television news showed footage of student survivors of the violence marching on the Florida state Capitol, calling for tougher laws. The protests came closer to Trump, too, with hundreds of students from suburban Maryland attending a rally at the Capitol and then marching to the White House. 1321
