When Tamerlan and Dzhokhar Tsarnaev bombed the finish line of the Boston Marathon a year ago, Russia and the U.S. were still at least frenemies. Now, as the two countries are increasingly at loggerheads over the situation in Ukraine, a new report has found that Russia withheld potentially critical information from the FBI that could have helped the U.S. nab Tamerlan Tsarnaev before the bombing, according to The New York Times.
"They found that the Russians did not provide all the information that they had on him back then, and based on everything that was available the FBI did all that it could," a senior American tells The Times. The report, from the inspector general of the intelligence community, has not been made public, but it reportedly largely exonerates the FBI. So what did Russia fail to do?
First, here's what Russia did do: In 2011, after Tamerlan visited the restive Russian province of Dagestan, Russian officials told the FBI that he "was a follower of radical Islam and a strong believer" and "had changed drastically since 2010 as he prepared to leave the United States for travel to the country's region to join unspecified underground groups," The Times reports.
Based on these warnings, the FBI examined Tamerlan's school, criminal, and internet records, and interviewed him, his parents, and friends. When that turned up nothing, FBI agents in Moscow asked Russian intelligence for more information. Russia declined. After the bombing, Russia turned over some other information, like an intercepted call between Tamerlan and his mother in which they discussed Islamic jihad. According to the inspector general's report, that information could have given the FBI more legal authority to monitor Tamerlan.
That's a lot of what-ifs. It does sound like Russia could have been more generous with its intelligence, but it's also still kind of incredible that Russia and the U.S. were sharing the fruits of their spying at all. This final quote, from a senior U.S. official to The New York Times, kind of sums it up: "Had [the FBI] known what the Russians knew they probably would have been able to do more under our investigative guidelines, but would they have uncovered the plot? That's very hard to say." It always is with counterfactuals. Peter Weber
Beyonce dropped her new single "Formation" on Saturday, and fans were able to listen to it live for the first time during the Super Bowl 50 halftime show. The performance — complete with a Beyonce army and a uniform inspired by Michael Jackson's 1993 Super Bowl attire — then shifted gears, and Beyonce paired up with Bruno Mars for a mashup and dance off. Watch the performance below. Catherine Garcia

Fans of the Denver Broncos and Carolina Panthers went all out for Super Bowl 50, donning their wackiest wigs, outfits, and accessories for the big game (all in shades of orange and blue, of course), with some even going so far as shaving the number of their favorite player into their hair. Here's a look at some of the biggest fans at Levi's Stadium. Catherine Garcia
Jordan Norwood of the Denver Broncos set a record on Sunday for the longest punt return in Super Bowl history.
Norwood caught the ball and sprinted for 61 yards before being ran down by Mario Addison on the Panthers' 14-yard-line, NBC Sports reports. The new record shatters the previous one made by John Taylor, 45 yards, during Super Bowl XXIII. Catherine Garcia
Carolina Panthers quarterback Cam Newton is known to celebrate first downs and touchdowns by "dabbing," but did you know it was actually Betty White who taught him everything he knows about the dance craze? Okay, that might not be entirely true, but White is certainly taking credit for it in a new CBS Sports video. Watch everyone's favorite golden girl show off her moves in the video below.

Before Super Bowl 50 began, the MVPs from previous years were celebrated during a ceremony at Levi's Stadium.
Former football stars Joe Montana, Joe Namath, Jerry Rice, Steve Young, and Ray Lewis were cheered, but one player wasn't shown the same respect — Patriots quarterback Tom Brady, who instead was booed by the crowd. Watch the video below. Catherine Garcia
