Michigan Gov. Rick Snyder activated the state's Emergency Operations Center to monitor the reentry of China's Tiangong-1 space station, which is expected to reenter the Earth's atmosphere between March 29 and April 2.While most of the space station is expected to burn up during reentry, there is concern that debris could make landfall. According to the Aerospace Corporation, the 8.5 ton space station could land along a strip of the United States from northern California to Pennsylvania, which includes the southern lower peninsula of Michigan. “While the chances are slim that any of the debris will land in Michigan, we are monitoring the situation and are prepared to respond quickly if it does,” said Capt. Chris A. Kelenske, Deputy State Director of Emergency Management and Homeland Security and commander of the Michigan State Police, Emergency Management and Homeland Security Division (MSP/EMSHD). “The state will rely on its existing satellite reentry response and recovery plan for any necessary response protocols.”Debris could contain hydrazine, which is a highly toxic and corrosive substance. Any suspected space debris should be considered hazardous.Anyone who suspects they've encountered debris from the space station should report it by calling 911 and stay at least 150 feet away from it. 1330

Microsoft took legal steps to dismantle a system that has allowed criminal hackers to infect more than a million computing devices since 2016, in order to protect the 2020 election.The technology company obtained a court order from a federal judge in Virginia that gives Microsoft control of the Trickbot botnet.Microsoft, along with partners around the world, were able to make it so those operating Trickbot cannot initiate new infections or activate ransomware already in computer systems.Trickbot botnet is a global network believed to be run by Russian-speaking criminals, and is “one of the world’s most infamous botnets and prolific distributors of ransomware” according to a blog post by Tom Burt, Corporate Vice President at Microsoft.Burt says ransomware is “one of the largest threats to the upcoming elections,” and can be used to “infect a computer system used to maintain voter rolls or report on election-night results, seizing those systems at a prescribed hour optimised to sow chaos and distrust.”The move by Microsoft represents a “new legal approach” the company says they are using for the first time.In addition to protecting election systems, Microsoft says dismantling Trickbot will also protect financial services institutions, government agencies, healthcare facilities, educational institutions, and other businesses subject to malware infections. 1382

Michael Cohen's stunning guilty plea last week ended months of speculation about the fate of President Donald Trump's longtime personal lawyer.And now, as Cohen waits for his sentencing hearing set for December, a source familiar with his thinking says "resignation" would be a fitting word to describe the 52-year-old's mindset -- acceptance that he is headed to prison in order to protect his family."He's very resigned to doing the time. He's resigned to the fact that he's going to go to jail for some time," the person said, adding that Cohen does not believe he will receive a presidential pardon from Trump. 622

Melania Trump is slamming Joe Biden, Democrats, and the media as she campaigns for her husband in Pennsylvania.WATCH RECAP:In her first solo appearance of the presidential campaign, Mrs. Trump says Democrats focused on a “sham impeachment” instead of the coronavirus pandemic. "The Democrats have decided to put their own agenda ahead of the American people's well-being," Melania said. "Instead, they attempt a divide, a divide on something that should not be non-partisan. A divide that causes confusion and fear instead of hope and security."She denounced what she called Biden’s “socialist agenda” and criticized media coverage of “idle gossip and palace intrigue.”Melania Trump also defended President Donald Trump’s record on COVID-19 even as he continues to downplay the threat of a virus that has killed more than 226,000 Americans."We all know the American spirit is stronger than this virus," the First Lady stated to the crowd in Pennsylvania. "We have proven that we can and will overcome this unexpected challenge."Her husband's chief of staff, Mark Meadows, said over the weekend that the U.S. is not going to be able to contain the virus.The first lady’s event 50 miles (80 kilometers) west of Philadelphia drew a couple of hundred supporters who piled into a converted barn typically used for wedding receptions. The overwhelming majority wore masks, but there was little social distancing.Mrs. Trump was diagnosed with the coronavirus earlier this month along with her husband, and she decided against attending a rally with the president last week because she was still feeling lingering symptoms. 1623
