Medina Spirit failed another drug test

A horse is a horse, of course, unless the horse is Medina Spirit. The New York Times reported Wednesday a split sample of Medina Spirit’s drug test after the Kentucky Derby confirmed the presence of betamethasone, further jeopardizing the horse's status as the winner of the race. Lawyer Clark Brewster, who represents Medina Spirit's owner Amr Zedan, said the laboratory at the University of California, Davis confirmed the presence of betamethasone, a corticosteroid. Though legal as a therapeutic aid for horses, betamethasone is illegal when found in the blood on race day because it’s a possible performance enhancer. Churchill Downs said Medina Spirit would be disqualified as the Kentucky Derby winner if a second test came back positive. If that happens, runner-up Mandaloun would be declared the winner.

Hackers target meatpackers

In the wake of a massive cyberattack, JBS USA, the world's largest meat supplier, has had shutdowns at nine of its U.S. beef plants. Officials expect to ramp production back up starting Wednesday. All of the company's meatpacking facilities in the USA have experienced some disruption to operations, union officials said. JBS halted processing at its five biggest beef plants in the USA, which handle more than 22,000 cattle a day. Reuters reported JBS had stopped livestock slaughter at plants in several states. The company's CEO, Andre Nogueira, said in a statement that "the vast majority of our beef, pork, poultry and prepared foods plants will be operational tomorrow.”

Capitol riot suspect pleads guilty

Pictured carrying a Trump flag on the Senate floor during the Capitol riot, a Florida man entered a guilty plea Wednesday for his role in the assault. Paul Hodgkins, 38, of Tampa, pleaded guilty to a lone count of obstructing a government proceeding, one of five criminal charges initially lodged against him. He could face a maximum punishment of 20 years in prison, but prosecutors recommended a reduced sentence because of his cooperation with authorities and clean criminal record. During the hearing, Hodgkins acknowledged that he was not permitted to enter the Capitol where he joined the mob that sought to disrupt the confirmation of President Biden's election win. One of more than 400 suspects swept up in the federal investigation, Hodgkins is the second to enter a guilty plea.

Coach K headed for retirement

A big winner is leaving college basketball. Duke men's coach Mike Krzyzewski, "Coach K," will retire after this coming season, according to a report Wednesday, ending a wildly successful run that began more than 40 years ago and included more than 1,000 wins and five national championships. Krzyzewski, 74, is the winningest coach in college basketball history with 1,170 victories, with all but 73 coming with the Blue Devils. After three rebuilding seasons to start his tenure, which began in 1980, Krzyzewski led Duke to the men’s NCAA Tournament in every year but one from 1984 through 2019. Krzyzewski was inducted into the College Basketball Hall of Fame in 2006.
