The Minnesota Vikings have fired general manager Kwesi Adofo-Mensah after mixed results over four seasons and giving him a contract extension last year. The Vikings appointed executive vice president of football operations Rob Brzezinski as the interim replacement through the NFL draft. The search for a new general manager will take place after that. Vikings owners Zygi Wilf and Mark Wilf said they made the decision following their annual end-of-season organizational meetings. The Vikings finished 9-8 and missed the playoffs for a second time in Adofo-Mensah’s four years. They didn’t win a postseason game.

NASA has delayed astronauts' upcoming trip to the moon because of near-freezing temperatures expected at the launch site. The first Artemis moonshot with a crew is now targeted for no earlier than Feb. 8, two days later than planned. NASA was all set to conduct a fueling test of the massive moon rocket on Saturday, but called everything off late Thursday because of the expected cold. The critical dress rehearsal is now set for Monday, weather permitting. The change leaves NASA with only three days in February to send four astronauts around the moon and back, before slipping into March.

Deputy Attorney General Todd Blanche says the Justice Department has opened a federal civil rights probe into the death of Alex Pretti. Blanche said Friday the department is "looking at everything that would shed light on that day.”

Kevin Warsh has sought the job of Federal Reserve chair, off and on, since President Donald Trump first considered him for the position nearly a decade ago. Now that he is in line for the job, the enormity of the challenge ahead of him is clear. To be effective, Warsh will have to gain the trust of the committee of Federal Reserve officials, the financial markets, and not least Trump. Warsh may also face a bumpy confirmation process in the Senate, where two Republicans have said they will oppose his nomination unless a recently-revealed criminal investigation of the Fed and its current chair, Jerome Powell, is resolved.

The Detroit Opera is showcasing Parliament-Funkadelic in a new way. George Clinton’s and P-Funk’s greatest hits will be performed by an orchestra. The event, titled “Symphonic PFunk-Celebrating the Music of Parliament Funkadelic,” takes place Saturday at the Detroit Opera House. Violins, cellos, horns, and more will bring some of the group’s classics to life. The 84-year-old Clinton says going classical is something he has been expecting to happen at some point with the group’s music. Detroit Opera has assembled 47 players, including a full string section and a harp, to perform these iconic tunes.

The Trump administration has imposed sanctions against Iran’s interior minister, accusing Eskandar Momeni of repressing nationwide protests that have challenged Tehran’s theocratic government. The penalties are the latest by the United States and the European Union targeting high-ranking officials over the crackdown. The administration says Momeni has overseen Iran’s law enforcement forces that are responsible for the deaths of thousands of peaceful protesters. The EU on Thursday imposed its own sanctions against Momeni, along with members of Iran’s judicial system and other high-ranking officers.

A judge has ruled that federal prosecutors can’t seek the death penalty against Luigi Mangione in the killing of UnitedHealthcare CEO Brian Thompson. U.S. District Judge Margaret Garnett's ruling Friday foiled the Trump administration’s bid to see Mangione executed for what it called a “premeditated, cold-blooded assassination that shocked America.” Garnett dismissed a federal murder charge against Mangione, finding that it was technically flawed. She left in place stalking charges that carry a maximum punishment of life in prison.

President Donald Trump says he’ll tap former Federal Reserve governor Kevin Warsh as the next Fed chair to replace Jerome Powell in May. The appointment, which requires Senate confirmation, amounts to a return trip for Warsh, 55, who was a member of the Fed’s board from 2006 to 2011. He was the youngest governor in history when he was appointed at age 35. He is currently a fellow at the right-leaning Hoover Institution and a lecturer at the Stanford Graduate School of Business. Prior to serving on the Fed’s board in 2006, Warsh was an economic aide in George W. Bush’s Republican administration and was an investment banker at Morgan Stanley.

The Westminster Kennel Club Dog Show is celebrating a milestone. The 150th annual show opens Saturday and culminates with the best in show prize Tuesday night New York's Madison Square Garden. What's now the most famous dog show in the United States began when some 19th-century New York gentleman hunters organized an event to compare their dogs. That first show, in 1877, was no small thing, featuring about 1,200 dogs of dozens of breeds. This year’s show boasts 2,500 dogs, representing as many as 212 breeds and 10 “varieties.” Club President Donald Sturz says the trappings have changed over time, but the love of dogs remains the heart of the show.
