If it ain't broke, don't fix it — but if you don't like it, shoot it.

Sen. Joe Manchin's (D-W.Va.) campaign is sticking with a tried-and-true strategy in a new ad released Monday — taking a shot at a lawsuit from his opponent to show just how much he disagrees.

Manchin, who is running against West Virginia Attorney General Patrick Morrisey (R), revived his own viral 2010 ad, in which he was filmed shooting a climate change bill he disliked. This time, he's reassuring his constituents that he wants to retain the Affordable Care Act's protection of pre-existing conditions.

"Hey, I haven't changed," Manchin tells the camera after replaying footage from 2010, "I might be a few years older, but I'll still take on anyone that messes with West Virginia."

With a guitar twanging in the background, Manchin tells voters that the new threat is a lawsuit that Morrisey joined that would dismantle elements of the ACA. "He is just dead wrong," says Manchin, pulling the trigger. Watch the ad below. Summer Meza

President Trump's administration is again ramping up its anti-refugee efforts. And this time, people who fled the Vietnam War are in the crosshairs.

Vietnam and the U.S. established diplomatic ties in 1995, and immigrants who arrived in America before then were protected from deportation under a 2008 agreement. But the Trump administration now believes the agreement doesn't actually protect them, a spokesperson for Hanoi's U.S. embassy tells The Atlantic, and it might start sending some of them back.

Trump has a long track record of opposing refugee resettlement, from reducing America's cap on how many refugees it will accept per year to moving to end protections that spare at-risk immigrants from deportation. Just Tuesday, Trump officials moved to deport 46 Cambodian immigrants legally living in the U.S., The New York Times reported.

This latest refugee crackdown came as Trump officials met with Washington's Vietnamese embassy, with an advocacy group telling The Atlantic they discussed reworking the 2008 agreement. A previous reinterpretation of the deal under Trump decided its protections didn't apply to "pre-1995 arrivals with criminal convictions," The Atlantic writes. A handful of Vietnamese immigrants were deported after the August decision.

Officials from Vietnam and the U.S. protested the change, and both countries' governments tried to reason further with the White House, America's ambassador to Vietnam through October of this year says. But Trump officials are still moving to strip the 2008 deal's protections from all pre-1995 immigrants — many of whom fled the Vietnam War and have obviously lived in America for decades.

A spokeswoman for the Department of Homeland Security said "we have 5,000 convicted criminal aliens from Vietnam with final orders of removal" and "it's a priority of this administration to remove" them. Read more at The Atlantic. Kathryn Krawczyk

British Prime Minister Theresa May has won a vote of confidence among her party with 200 votes in favor and 117 against, BBC reports.

The vote comes just after May said she wouldn't lead her party in 2022's general election, and protects her from immediately being forced out in favor of new leadership. But its "not all comfortable" margin signals a "blow" to May's authority, BBC's Laura Kuenssberg says.

Confidence in May's leadership has dwindled in the past few days as her plan to remove the U.K. from the European Union stalls in Parliament. May tried to have members of Parliament vote on her Brexit plan earlier this week, but she postponed the vote over fears it might fail. Pro-Brexit members from May's Conservative Party then triggered a no-confidence vote against her. If May had lost the vote with a majority, or 158, of Conservatives voting against her, the party would've elected a new leader.

Sensing her party's resistance to her leadership, May told Conservatives earlier that she wouldn't lead them into the country's next general election and may step down as soon as Brexit goes through. May's narrow win on Wednesday signals just how strong that resistance seems to be.

Britain voted more than two years ago to leave the E.U., and lawmakers have since fought over how close to remain with the trading bloc. The U.K. is scheduled to leave the E.U. in March, despite a the country remaining far from reaching a deal to do so. Kathryn Krawczyk

The Great Barrier Reef may not be so doomed after all.

Hundreds of the Australian reef's coral species are blossoming deeper in the ocean than biologists previously thought, a report published by The Royal Society on Tuesday reveals. Growing further from direct sunlight could save these species from coral bleaching caused by climate change and prove essential for their conservation, Science News says.

The world's largest coral reef has been decimated as climate change warms waters and strips corals of their bright colors, killing them. Deeper-growing corals are safer from climate change, but scientists thought only a few species could grow more than 100 feet from the surface. It turns out 195 species can actually grow in the shady, cold depths and not just near the sun, per the study. So when shallow-water corals die off, scientists might be able to "transplant" these "deep ocean corals" and repopulate the surface, Science News writes.

The study was published just two days after another promising reef report. Though bleaching may severely damage of Great Barrier Reef, corals that survived one season tended to tolerate hotter temperatures the following year, a study published Monday in Nature shows. It's not great that any corals are dying, scientists assure, but at least this suggests the strongest ones will live on and repopulate the reef. Kathryn Krawczyk

The House and Senate are finally tackling a big problem happening in their own halls.

The two chambers on Wednesday agreed on a bill to better handle sexual harassment in Congress, Sen. Roy Blunt (R-Mo.), a co-sponsor of the Senate's version of the bill, tells Politico. Other congressional staffers confirmed the news to The Washington Post and CNN.

Following the #MeToo movement's rise late last year, members of Congress started looking inward at the harassment aides and lawmakers had long faced. The reality became particularly clear after former Rep. Blake Farenthold (R-Texas) allegedly used taxpayer money to settle a sexual harassment lawsuit, and after he and other lawmakers stepped down after their own sexual harassment scandals.

The House passed its harassment-fighting bill in February, under which lawmakers would be held "personally liable for harassment and discrimination settlements," per Politico. The Senate's latest version only made legislators pay for harassment settlements. Wednesday's compromise agrees on barring legislators from using taxpayer money to settle "harassment and retaliation for harassment claims, but not discrimination," staffers tell Politico.

Opponents of the Senate bill worried accused congressmembers would settle harassment claims as "sex discrimination," per CNN. So Reps. Jackie Speier (D-Calif.) and Bradley Byrne (R-Ala.) say they'll craft a new bill to address discrimination, per Politico. The two chambers hope to pass the still-unfinalized bill within the next few days after working out a few more specifics, Blunt says. Kathryn Krawczyk

For Star Wars fans, the new TV show's latest casting news is a surprise, to be sure, but a welcome one.

After it was reported that the upcoming live-action series The Mandalorian would star Pedro Pascal (Game of Thrones), Lucasfilm confirmed the choice on Wednesday and announced seven additional members of the cast, including none other than Werner Herzog. Yes, that Werner Herzog: the 76-year-old German director who might be one of the very last people you'd expect to see cast in a Star Wars project. He's taken some acting roles in the past like in Jack Reacher and had previously been rumored for a part in the series, but while it might have seemed too good (and weird) to be true, it's official now.

Also joining the cast of The Mandalorian is Giancarlo Esposito, best known for playing Gus Fring on Breaking Bad and Better Call Saul, and Carl Weathers, best known for his role as Apollo Creed in the Rocky series. Other members of the cast include Emily Swallow (Supernatural), Gina Carano (Deadpool), Omid Abtahi (American Gods), and Nick Nolte (Affliction).

The Mandalorian is set to follow the adventures of a lone gunfighter, played by Pascal, in the galaxy's outer reaches a few years after the events of 1983's Return of the Jedi. It's currently in production under the stewardship of Jon Favreau (The Jungle Book) and will be an exclusive to the Disney+ streaming service, which launches in late 2019. Brendan Morrow

After Time's person of the year shortlist reminded us all what a decade this year has been, Google is here to hammer that point home even further.

Google on Wednesday released its annual "year in search" list, which takes a look at which topics earned the biggest spike in Google search traffic in 2018 compared to the year before. It reveals that the No. 1 global search trend of the year was the World Cup, which, despite how it might feel, was only five months ago. The next two most popular search topics concern two musicians who died suddenly at a young age: Avicii, who committed suicide in April, and Mac Miller, who died of a drug overdose in September.

Marvel Comics creator Stan Lee, who died in November, took the fourth spot, and the fifth is the Marvel Studios' film Black Panther, which was released in February and saw the biggest search spike of any movie in 2018.

Meghan Markle, Duchess of Sussex, topped the list of most popular people, followed by singer Demi Lovato, actor Sylvester Stallone, YouTuber Logan Paul, and reality TV star Khloé Kardashian. The World Cup also topped the list of news events, followed by Hurricane Florence, the Mega Millions results, the Royal Wedding, the election results, Hurricane Michael, and Brett Kavanaugh's Supreme Court confirmation.

All of the lists look a bit different when specifically honing in on the U.S., though. The World Cup also had the biggest search spike domestically, but in America, designer Kate Spade and chef Anthony Bourdain made the top five searches after being further down the list worldwide. The biggest movie in the U.S. was Black Panther, the biggest video game was Fortnite, the biggest TV show was Roseanne, the biggest song was "Bohemian Rhapsody," the biggest athlete was Tristan Thompson, and the biggest politician was Stacey Abrams.
