All about the Super Bowl, a look at potential politics in 2024, and more top news from the past week

PHOENIX (AP) — The Kansas City Chiefs welcomed two new fans to the world on Super Bowl Sunday with a third apparently on the way.

Chiefs offensive lineman Nick Allegretti's wife, Christina, gave birth in the early hours to twin girls back home in Chicago, a team official confirmed to The Associated Press. Allegretti was able to watch everything unfold on FaceTime from the lobby of the team hotel while the rest of the Chiefs slept ahead of their game against the Philadelphia Eagles.

GLENDALE, Ariz. (AP) — Rihanna was pregnant with her second child as she performed her Super Bowl halftime show Sunday.

The singer's representative confirmed the pregnancy shortly after she ended her 13-minute set at Super Bowl 57.

Country star Chris Stapleton made the national anthem a simple affair at Super Bowl 57, standing alone on the field accompanied by only his electric guitar as he sang "The Star Spangled Banner" moments before the Kansas City Chiefs kickoff to the Philadelphia Eagles to start the game.

Dressed simply in smooth black denim and sunglasses, with neatly combed hair instead of his signature feathered cowboy hat, he sang the anthem as a plaintive ballad, picking it up to rock only briefly as he delivered the final lines "banner yet wave" and "land of the free!"

VANCOUVER, British Columbia — Canadian Prime Minister Justin Trudeau said Saturday that on his order a U.S. fighter jet shot down an "unidentified object" that was flying high over the Yukon — a day after the U.S. took similar action over Alaska.

North American Aerospace Defense Command, the U.S.-Canada organization that provides shared defense of airspace over the two nations, detected the object flying at a high altitude Friday evening over Alaska, U.S. officials said. It crossed into Canadian airspace on Saturday.

GLENDALE, Ariz. (AP) — The Super Bowl had something for everyone.

Long before Patrick Mahomes and the Kansas City Chiefs lifted the Vince Lombardi Trophy, the biggest winner of this NFL season walked onto the field. Damar Hamlin came out to a rousing ovation during a pregame ceremony honoring the men and women who saved his life.

GLENDALE, Ariz. (AP) — Patrick Mahomes shook off an ankle injury, turned back into a magician and pulled out another comeback on the biggest stage to help the Kansas City Chiefs win their second Super Bowl in four years.

Mahomes threw two touchdown passes in the fourth quarter and scrambled 26 yards on the go-ahead drive before Harrison Butker kicked a 27-yard field goal with 8 seconds left to give the Chiefs a 38-35 victory over the Philadelphia Eagles on Sunday night.

EAST LANSING, Mich. (AP) — The gunman who killed three students and wounded five at Michigan State University was a 43-year-old with a previous gun violation who fatally shot himself after an hourslong manhunt that ended in a confrontation with police miles from campus, officials said Tuesday.

Investigators still were sorting out why Anthony McRae fired inside an academic building and the student union shortly before 8:30 p.m. Monday. The shootings led to a harrowing campus lockdown and a search for the gunman that ended roughly three hours later.

ATLANTA (AP) — A Georgia judge on Monday ordered the partial release later this week of a special grand jury report into efforts by former President Donald Trump and his allies to overturn his 2020 election loss.

The report's introduction and conclusion, as well as a section in which the grand jurors expressed concerns that some witnesses may have lied under oath, will be released on Thursday, said Fulton County Superior Court Judge Robert McBurney.
