Julián Castro went straight for the jugular during Thursday night's Democratic debate, telling former Vice President Joe Biden that when it comes to health care, "I'm fulfilling the legacy of Barack Obama, and you're not."

Castro told Biden that his health care plan would leave 10 million people without coverage, while he wants "every single American family to have a strong Medicare plan available. If they choose to hold on to strong, solid private health insurance I believe they should be able to do that, but the difference between what I support and what you support, Vice President Biden, is that you require them to opt-in, and I would not require them to opt-in." He added, "Barack Obama's vision was not to leave 10 million people uncovered. He wanted every single person in this country covered. My plan would do that, your plan would not."

Biden interjected, saying people would not have to buy-in under his plan. "Are you forgetting what you said two minutes ago?" Castro shot back, a line that earned "oooohs" from the audience. "If you lose your job, for instance, his health care plan would not automatically enroll you, you would have to opt in," Castro continued. "That's the big difference — I'm fulfilling the legacy of Barack Obama and you're not." In response, Biden muttered, "That'll be a surprise to him." Cue more "oooohs."

It appears as though it's actually Castro who forgot what happened two minutes ago, several Twitter fact-checkers said. Julie Rover, chief Washington correspondent for Kaiser Health News, tweeted that Biden's plan would actually "auto-enroll everyone under 138 percent of poverty — the population currently eligible for the Medicaid expansion in states that have adopted it."

The Daily Beast's Sam Stein also backed Biden's version of events, saying that he "re-watched the segments where Biden talked health care and it seems pretty clear to me that Castro is, well, wrong. He never said opt-in. He said that if people lose their jobs they can automatically buy into Medicare." Stein later tweeted a follow-up, revealing that "In fact, Biden at one point said the opposite: 'Anyone who can't afford it gets automatically enrolled in the Medicare-type option we have.'"

Disney+ has officially become part of your streaming world.

The brand new Disney streaming service officially launched in the U.S. on Tuesday morning, debuting with the first episode of the live-action Star Wars TV series The Mandalorian. As promised, the premiere featured a bombshell reveal for the franchise that sparked quite a bit of Twitter buzz. Other originals available at launch include the new live-action Lady and the Tramp movie and High School Musical: The Musical: The Series.

The Disney+ library also boasts tons of films from throughout the studio's history, including its animated classics, plus Star Wars and Marvel films, although not everything is available immediately; some movies, like Star Wars: The Last Jedi, are tied up on Netflix for now.

Also available on Disney+ is Avengers: Endgame, which became the highest-grossing film of all time earlier this year and originally wasn't expected to debut on the service until December. Films have a separate tab on the service for bonus features, and Endgame's section includes a previously-unreleased deleted scene in which Katherine Langford plays an older version of Tony Stark's daughter in a vision sequence.

The Disney+ launch comes less than two weeks after Apple also entered the streaming market with its own streaming service, Apple TV+, which costs $4.99 per month. Disney CEO Bob Iger has described Disney+ as a "bet on the future of this business," clearly having realized that streaming ain't no passing craze. Brendan Morrow

The Supreme Court will hear 80 minutes of oral arguments Tuesday from defenders and opponents of the Deferred Action for Childhood Arrivals (DACA) program, which shields about 660,000 immigrants who grew up in the U.S. from deportation. Texas and 12 other states are challenging the legality of the program, instituted by former President Barack Obama in 2012, but lower courts in California, New York, and Washington, D.C., have blocked President Trump's plans to end the program, citing Trump's violations of the Administrative Procedure Act.

Until the Supreme Court hands down its decision, the young immigrants — or DREAMers — already in the program can renew their 2-year work and residency permits but new DREAMers can't enroll in the program. One of the lawyers defending DACA at the Supreme Court is a DREAMer from Washington State. The lead advocate for the program on Tuesday will be famed litigator Theodore Olson, joined also by California's solicitor general. Peter Weber

Former Massachusetts Gov. Deval Patrick (D) is preparing to enter the crowded Democratic presidential race as soon as this week, two people with knowledge of his plans told multiple news organizations Monday. He will presumably decide by Friday, the filing deadline for the New Hampshire primary. Patrick, 63, served as governor from 2007 to 2015. Democratic voters say they are pleased with the current crop of Democratic candidates, but some wealthy donors and Wall Street executives have expressed concerns about Sen. Elizabeth Warren's (D-Mass.) rise and the stalled prospects of more moderate former Vice President Joe Biden. Patrick is one of the candidates they have been trying to lure into the race; another candidate, former New York City Mayor Michael Bloomberg, made his own late forays into the race last last week.

Patrick brings a strong résumé and compelling biography, but he's also trying to extricate himself from Bain Capital, the private equity firm co-founded by Mitt Romney, and has some family baggage. When he announced he wouldn't run last December, Patrick cited "the cruelty of our elections process" and how it would "splash back" on people he loves. Patrick's reconsideration "is coming from Wall Street," a source tells Politico. "They're terrified of Warren. And these guys would help Biden. But they've been in a room with him up close and they have doubts. ... Deval wants this. He regrets not having done it. His wife was ill. But since then, she has gotten better. But the field has gotten worse." Peter Weber

Former President Jimmy Carter was admitted to Emory University Hospital in Atlanta on Monday evening to prepare for a Tuesday morning operation to "relieve pressure on his brain, caused by bleeding due to his recent falls," the Carter Center said in a statement. Carter, who recently turned 95, is the oldest living ex-president ever. He has fallen at least three times this year, including one tumble that required a hip replacement in the spring and a pelvis fracture on Oct. 21. In 2015, Carter was diagnosed with brain cancer and then declared cancer-free.

In between health scares, Carter had been building houses with Habitat for Humanity and teaching Sunday school at Maranatha Baptist Church in his hometown of Plains, Georgia. "We just need the whole country to be in prayer for him," Carter's pastor, Rev. Tony Lowden, told The Associated Press. Peter Weber

Former Vice President Joe Biden answered questions at a CNN town hall in Grinnell, Iowa, on Monday night. The most contentious moment was when an audience member asked Biden why he doesn't support Medicare-for-all, and Biden used the occasion to escalate his barely veiled feud with Sen. Elizabeth Warren (D-Mass.) and, to a lesser extent, Sen. Bernie Sanders (I-Vt.).

Biden called the Medicare-for-all plan too expensive, politically unattainable, and "elitist," arguing that switching to only a government-run health care plan conveys "the attitude that we know better than ordinary people what's in their interests." When pressed on his attacks on Warren specifically, Biden said that "she attacked me" first, later asserting that he isn't calling Warren herself "elitist," exactly. "It's not about her, it's about the attitude out there — the attitude that we know best, you do it my way," he said. "I resent that. And I wasn't talking about her, I was talking about the attitude that if you don't agree with me, get in the other party."

Biden also gave contradictory assessments of how congressional Republicans would act if a Democrat defeats President Trump. First he discussed calling 12 Republican senators when the GOP-led Senate stonewalled President Barack Obama's Supreme Court nominee Merrick Garland in 2016, recounting that they told him they knew they were shredding the Constitution, but "Joe, I'm in a state where if in fact the Koch brothers drop in $10, $12 million, I will lose the primary.'" Biden also said, without explaining his thought process: "I honest to God believe, with Trump out of the way, you're going to find people screwing up a lot more courage than they had before to say, 'Okay, okay, I can move now, I have more leeway.'"

And Biden shrugged off the electoral impact of the House impeaching Trump, saying "the House has no option, it has to enforce the Constitution," and arguing that if Democrats make a strong case against the president, some independents and Republicans will be persuaded. Peter Weber

"Right now, the Democratic Party has an option for everyone," Trevor Noah said on Monday's Daily Show. "There's moderates, there's progressives, there's X-Men, and there's even a guy who's worth $1.6 billion. But what if $1.6 billion just isn't rich enough for some voters? Well then, those people might be in luck." That's because billionaire former New York City Mayor Michael Bloomberg "is on the verge of jumping into the Democratic primary, because he doesn't think any of the current candidates can beat Trump," he said. "And you have to admit, that's such a billionaire thing to do."

"Bloomberg may be making a fashionably late entrance into the presidential race, and his fellow Democrats aren't exactly giving him a warm welcome," Noah said, with a special laugh for Sen. Bernie Sanders' (I-Vt.) reaction. So why is Bloomberg running? Reportedly, "Jeff Bezos told Bloomberg to run," he said. "You know you're rich when the Amazon guy orders something from you! That's money."

"Wow, he just ordered up a presidential candidate — what level of Amazon Prime is that?" Seth Meyers echoed at Late Night. "Bloomberg's interest in running and Bezos' prodding come after weeks of billionaires freakouts over the possibility that someone who's critical of big banks and Wall Street like [Sen. Elizabeth] Warren or Bernie could get the Democratic nomination. In fact, last week even Bill Gates expressed concern about how much he personally would have to pay in taxes and joked that he might not have that much left over." Warren trolled Bloomberg and Gates with their own internet calculators for billionaires.

"In reality, the vast majority of Democratic primary voters say in polls that they're actually satisfied with the choices they already have," Meyers said. "People aren't just mad at billionaires out of jealousy or because candidates demonize them. There are real-world examples that are informing people's doubts that the wealthy can solve everything," or anything. Watch below. Peter Weber
