Hillary Clinton spoke at Yale's Class Day on Sunday, referencing the university's tradition of wearing silly (typically DIY) hats for the occasion by bringing a Ushanka hat along for a predictable joke about President Trump. "A Russian hat," she said, waving but not actually wearing it. "If you can't beat 'em, join 'em."

Clinton also revisited her loss to Trump in a more serious tone. "I'm not over it," she said. "I still think about the 2016 election. I still regret the mistakes I made. I still think, though, that understanding what happened in such a weird and wild election in American history will help us defend our democracy in the future."

For three months during the Korean War, 1,000 sailors aboard the USS Point Cruz doted on a tiny passenger: a baby rescued from a trash can in Seoul.

While on a walk, Navy medic Norm Van Sloun of Minnesota and a few other sailors heard a cry, and that's when they found the baby, left for dead. He was half-Korean, with blonde hair and blue eyes, and Van Sloun told WCCO at the time, orphanages "wouldn't have anything to do with Caucasian babies." So, he was brought on board, and within five hours, carpenters had a crib ready for him and a sick bay was transformed into a nursery.

The baby was named George Ascom Cruz — ASCOM after the compound where he was found, and Cruz in honor of the aircraft carrier. He spent three months on board, and during that time, the skipper flew a diaper right below the American flag. The baby had visiting hours, and the sailors would "all line up to come see George," Van Sloun said. "It was amazing."

Van Sloun always wondered what happened to George, and so did his children, who grew up hearing stories about the baby their father found. His daughter Mary Beth Bouley recently posted about George online, and it didn't take long for him to get in touch. His name is now Dan Keenen, and he was adopted by a Navy surgeon in Spokane. Keenen is married and has two sons, and couldn't wait to see Van Sloun.

They recently reconnected via video chat, with Van Sloun, now 88, reminiscing with Keenen about the time they spent together. He remembered singing Keenen to sleep, and the fact that newspapers around the world picked up the story about sailors raising a baby. Keenen told Van Sloun he could never fully convey just how much he appreciated what the sailors did for him, telling his rescuer: "If it weren't for these guys, I literally wouldn't be here today because I wouldn't have survived there."

Late Tuesday, Los Angeles teachers approved a contract deal and agreed to return to the classrooms on Wednesday after a six-day strike in the nation's second-largest school district. The votes of the 30,000 teachers union members were still being counted Tuesday night, but "a vast supermajority are voting yes for the agreement that we made," said union president Alex Caputo-Pearl. "Those are preliminary results but they're so overwhelming that we know what the results are going to be."

The deal, finalized early Tuesday, gives teachers a 6 percent raise, reduces class sizes incrementally over the next few years, and increases the number of support staff, including teachers and librarians. The Board of Education is expected to ratify the deal in short order. Caputo-Pearl called the agreement a "historic victory" for "educators, students, and parents" achieved through "unity, our action, and our shared sacrifice." Peter Weber

Pitcher Mariano Rivera made history on Tuesday, becoming the first player unanimously voted into the Baseball Hall of Fame.

Rivera, who played for the New York Yankees for 19 seasons, received a vote on all 425 ballots cast. Edgar Martinez, Roy Halladay, and Mike Mussina were also elected on Tuesday. In December, the Today's Game Era Committee picked Harold Baines and Lee Smith for induction. They will be honored during a ceremony July 21 in Cooperstown, New York.

With Rivera as a closer, the Yankees won five World Series titles. The 13-time All-Star was also named the MVP of the 1999 World Series. Before Rivera, Ken Griffey Jr. came the closest to being unanimously elected, receiving 99.3 percent of the vote three years ago. This was the first year Halladay, who died in a plane crash in November 2017, was on the ballot. The last player to be elected on the first ballot posthumously was Christy Mathewson in 1936, the Los Angeles Times reports. Catherine Garcia

A former Trump campaign aide told CNN on Tuesday that when he was interviewed by Special Counsel Robert Mueller's team, investigators asked him about how the National Rifle Association forged a relationship with the campaign.

Sam Nunberg said he was also questioned about President Trump's speech at the NRA's annual meeting in 2015, and how that opportunity came up. Nunberg was interviewed in February 2018, but CNN reports that as recently as a month ago, investigators were asking about ties between the NRA and the campaign.

The NRA spent $30 million to support Trump's candidacy, more than the organization spent on presidential, House, and Senate races combined in 2008 and 2012. People familiar with the matter told CNN that Mueller did not ask Trump about the NRA in the written questions he sent him.

Last month, Russian national Maria Butina pleaded guilty to conspiring against the United States, and has acknowledged forming friendships with prominent NRA members in order to gain access to GOP political circles. She said she was working under the direction of Alexander Torshin, a former Russian central banker and lifetime member of the NRA. Catherine Garcia

On Friday, three men and a juvenile were arrested in connection with an alleged plot to attack a predominately Muslim community in upstate New York, police in Greece, New York, announced Tuesday.

Islamberg is home to about 200 people, and was settled by followers of Pakistani cleric Sheikh Mubarik Gilani. During a press conference, Greece Police Chief Patrick D. Phelan said a 16-year-old at Greece Odyssey Academy showed a classmate a photo during lunch, and said the person looked "like the next school shooter." Police were tipped off, and during an interview with the teen, learned he was allegedly planning on attacking the Islamberg community, along with three men. At that point, "our investigation took us to this plot that we had no idea about," Phelan said.

Police arrested Brian Colaneri, 20, Vincent Vetromile, 19, Andrew Crysel, 18, and the 16-year-old on Friday. They discovered three improvised explosive devices at the juvenile's home, and through search warrants, found 23 legally owned shotguns and rifles. Phelan said the suspects began planning the attack about a month ago, and on Saturday, the adults were each charged with three counts of criminal possession of a weapon in the first degree and one count of conspiracy in the fourth degree. Due to the teenager's age, police did not release any information on his charges. Catherine Garcia

A judge in North Carolina on Tuesday rejected Republican candidate Mark Harris' request to certify the results of the state's disputed 9th congressional district race.

The final tally from the November election has Harris leading Democrat Dan McCready by 905 votes. The state's election board said it could not certify the results because it is investigating allegations that a man working on behalf of a firm hired by Harris illegally collected absentee ballots. To make things even more complicated, the election board that launched the investigation was ruled unconstitutional and dissolved, The News Observer reports, and the next board won't be created until Jan. 31 or later.

During the hearing, Wake County Superior Court Paul Ridgeway said "this is an extremely unusual situation, with no board in place, and asking this court to step in and exert extraordinary power in declaring the winner of an election, when that is clearly the purview of another branch of government." Harris and McCready did not attend the hearing, but afterwards, a spokesman for McCready said "the most important thing is that people get the answer they deserve," and he believes "both sides agree that it's important that the people of North Carolina have a voice in Washington."
