At the end of the month, there will be a referendum to decide if Britain should leave or remain in the European Union. The implications are radical for the United States: Following World War II, the EU brought stability and order to Europe, and as a single unit it has helped the U.S. with geopolitical responsibilities around the world. On the economic front alone, President Obama has urged against a Brexit, saying it could take as many as 10 years for Britain to negotiate new trade deals with the U.S.

"Brexit is not the source of Europe's trend of disintegration," Vox explains, "But if it happens, it could be the beginning of the end for the most successful U.S. foreign policy ever and a serious blow to U.S. efforts to maintain stability and order in Europe and therefore beyond."

In other words, it is a really big deal.

Enter Donald Trump:

"If there's any pattern to [Trump's] conversation, it's that he's vague on all subjects outside himself, his campaign, and the media. Everything else is mere distraction," Michael Wolff writes in The Hollywood Reporter. Perhaps Trump is so vague because he's just been called on and apparently hasn't done his homework.

President Trump came out on Tuesday with what he called a "clarification" of remarks he made in Helsinki on Monday, but CNN's Chris Cuomo and his giant computer screen weren't buying it.

While standing next to Russian President Vladimir Putin, Trump had an "epic fail in front of the world," Cuomo said, choosing Putin's "lies over his own country's truth." Trump on Tuesday said he misspoke, and meant to say "I don't know why it wouldn't be" Russia that meddled in the election, rather than "would." Cuomo had the portion of his remarks up on the screen, and ripped apart this explanation, going sentence by sentence.

Trump believes when the 2016 election is attacked, it "delegitimizes his win," Cuomo said, and "if it comes down to what is best for Trump or what is best for you, you're going to lose, and the world saw this yesterday and it was shameful." The most authentic proof of this is found in Trump's prepared remarks from Tuesday. They were typed, but Trump wrote in huge letters on top, "There was no colusion [sic]."

"Why?" Cuomo said. "Even though it has nothing to do with saying it is true that Russia attacked us, it is what he cares about, and you know it's authentic because he misspelled collusion and that is something he does, he misspells words." Trump also crossed out a line about bringing those involved "in that meddling to justice," and that's because "he hates the notion that there could be any sense of justice, fairness under law, that involves punishing him or anyone around him," Cuomo said. "The insistence on covering for himself cost our country a lot of legitimacy in Helsinki." Watch the video below. Catherine Garcia

Rep. Martha Roby was victorious Tuesday night, winning the Republican primary runoff in Alabama's 2nd congressional district.

She defeated Bobby Bright, a former Democratic congressman who became a Republican and vocal supporter of President Trump. After the Access Hollywood tape came out in October 2016 that showed Trump bragging about assaulting women, Roby said she would not vote for him, and that was used against her by Bright and the other Republican candidates during the campaign. In the June primary, Roby was unable to get more than 50 percent of the vote, and had to face Bright in the runoff election.

Since the election, Roby has praised Trump and visited the White House multiple times, and last month, he tweeted his endorsement of her. With nearly half of all precincts reporting, Roby had 67 percent of the vote, compared to Bright with 33 percent. Catherine Garcia

During a forum on gun control last week in Tucson, a Republican candidate for Arizona's Legislative District 2 stood up and said that he is proof of the importance of, in case of an attack, having a "good guy there with a gun."

Bobby Wilson said that when he was a teenager, he shot and killed a person who came into his room and wanted him dead, The Arizona Republic reports. "You can pass all the laws you want to in this world, and when you've got somebody out there that wants to harm somebody, they're going to do it if you don't stop them," he said.

The person he killed wasn't a burglar or a stranger, but rather his mother, Lavonne. Wilson was 18 and living in Hugo, Oklahoma, when the incident occurred. He said he woke up one morning "to find a rifle in my face," and he ended up having to dodge six bullets. He reached for the gun he kept under his bed, and used that to shoot his mom. The story doesn't end there, though. His younger sister, Judy, was also killed; Wilson said his mother swung her gun and accidentally hit her in the back of the head, killing the 17-year-old.

Wilson told The Arizona Republic there were glass containers in his room filled with gasoline, and when the bullets started to fly, several shattered. When he went to turn on the light, a spark landed on the ground and the house went up in flames. He said it wasn't until he became a lawyer years later did he remember all this, because he had amnesia after the shooting.

Newspaper reports from the time say Wilson confessed to shooting his mother, and when his sister ran at him, he crushed her skull with the rifle. He placed their bodies on a bed, then set the house on fire. He was tried on homicide charges, but after a jury agreed he had amnesia, the judge halted the trial until he could remember what happened. After seven years, Wilson asked for the charges to be dismissed, and a judge agreed. Read more about this bizarre tale at The Arizona Republic. Catherine Garcia

Walter Carr wasn't going to miss his first day of work, even if it meant getting up at midnight and walking 20 miles.

Carr, 20, lives in Homewood, Alabama, and he needed to get to Pelham, where he would start his job with the Bellhops moving company. His car had broken down, and he decided he would walk, so after just four hours of sleep, he set out on his journey. About 10 miles in, Carr had to take a break because his legs hurt, and a police officer pulled over to check on him. After hearing Carr's story, the officer and two others took him to breakfast, and he was dropped off at the home of Jenny Lamey.

When Lamey found out what Carr went through to get to her house, she asked him if he would like to rest, but he declined, and said he wanted to get to work. Carr told Lamey's children that when he was five, his home was destroyed during Hurricane Katrina, and also that after he earns his associate's degree later this year, he's going to start boot camp with the Marines. Lamey decided to start a GoFundMe to raise money for Carr to fix his vehicle, and she also shared his story with Bellhops CEO Luke Marklin, who was so impressed he drove from his home in Chattanooga to visit his "incredible" employee for lunch.

Carr didn't just get to share a meal with his boss, though. The Lamey family, the police officers he met, and his new Bellhops colleagues were waiting for him at a hotel, where Marklin surprised Carr with the keys to the Ford Escape SUV he drove to Alabama. "Walter truly raised the bar," he told ABC News. Carr was shocked, and said he was grateful and happy to have inspired so many people. Catherine Garcia

White House Chief of Staff John Kelly was so incensed by President Trump's press conference with Russian President Vladimir Putin on Monday that he called Republican lawmakers and gave them permission to speak out against Trump's comments, three people familiar with the matter told Vanity Fair's Gabriel Sherman.

Kelly warned Trump that by saying he had no reason to believe Russia would want to interfere in the 2016 presidential election, it made things infinitely worse for him with Special Counsel Robert Mueller, Sherman reports, and he also urged him to take back the remarks, which he kind of attempted to do on Tuesday.

Trump himself was surprised by the public's negative reaction to the press conference, but by the time he returned to the United States he was enraged that few people were defending him. "This was the nightmare scenario," one Republican close to the White House told Sherman. Catherine Garcia

Since Hurricane Maria ravaged homes in Puerto Rico last September, the Federal Emergency Management Agency has denied at least 335,748 applications for disaster assistance, and has either rejected or not responded to 79 percent of appeals.

It's hurricane season again, and for residents like Ramón Paez Marte, they are still dealing with damage done in 2017. He lives in Canóvanas, and his home is missing part of the roof and has a broken door. Paez Marte told NBC News he's applied for assistance, but has been told he's ineligible. FEMA requires people prove their houses were damaged, and they must be inspected by officials. Residents also have to prove their identities and home ownership status, but that's an issue in Puerto Rico, where houses are passed down, some are built without legal permits, and many don't have a title or deed.

Paez Marte gave FEMA a letter from the mayor of Canóvanas, which stated he had owned his home for about 20 years; his appeal was rejected, with FEMA saying he couldn't prove that was his house. "I don't live here because I want to," he told NBC News. "No one that lives here, lives here willingly. They're here because we truly have nowhere else to go." Catherine Garcia

Liz Cambage isn't just breaking records in the WNBA — she's standing beside the greatest players on the men's side too.

The Dallas Wings center scored 53 points against the New York Liberty on Tuesday, setting a new record for the most points scored by a WNBA player in a single game. The 6-foot-8 phenom toppled the record set by Los Angeles Sparks guard Riquana Williams in 2013, when she scored 51 points against the San Antonio Silver Stars while she was a member of the Tulsa Shock.

In helping the Wings to a 104-87 victory Tuesday, Cambage was clearly on point, going 17-22 from the field and 15-16 from the free throw line. She also nabbed 10 rebounds and blocked five shots. Bleacher Report's Natalie Weiner noted that the last basketball player to stuff the box score like Cambage did Tuesday was the one and only Michael Jordan.

Previously, Cambage's highest-scoring game was her 37-point performance against the Chicago Sky earlier this month. But with 44 seconds left in Tuesday's game against the Liberty, the Australian was able to sink a 3-pointer and secure her spot at the top. Watch Cambage make history below. Amari Pollard
