In May, the Trump administration rolled out a program it had been testing since last summer to charge everyone crossing the U.S.-Mexico border without proper documents with illegal entry, even asylum-seekers, a policy that "ends up systematically separating families because children can't go with their parents who are being detained by the U.S. Marshals," BuzzFeed News' Adolfo Flores explains. "But people charged with illegal entry go before a judge within days or weeks of their detention and are usually sentenced to time served for the misdemeanor. There appears to be no set procedure for what happens with parent and child after that."

Once the children are separated, they are handed over to the Health and Human Services Department's Office of Refugee Resettlement (ORR) "and treated as though they traveled to the U.S. alone," The New Yorker's Jonathan Blitzer adds. "No protocols have been put in place for keeping track of parents and children concurrently, for keeping parents and children in contact with each other while they are separated, or for eventually reuniting them. Immigration lawyers, public defenders, and advocates along the border have been trying to fill the void."

Immigrations and Customs Enforcement (ICE) spokeswoman Danielle Bennett told BuzzFeed News that "reunification typically does not occur until the removal stage of the process," and "the logistics of the reunification are made on a case-by-case basis." She declined to provide any statistics or give any examples of children successfully reunited with parents, saying, "We don't have any metrics to provide at this point and we wouldn't proactively give examples of this." Homeland Security Secretary Kirstjen Nielsen doesn't seem clear on some details, either.

Immigrant advocates say if there is a policy to track or reunite families, it isn't working on the ground. Peter Weber

President Trump appeared on Fox Business on Friday, and seemed to have a lot on his mind. Here are 4 of the most dubious things he told host Maria Bartiromo.

1. He's uniting the country. Well, part of it: Bartiromo asked if Trump feels a sense of "responsibility" to "bring the nation together." Trump confusingly said "I do, I do," but said he is doing it in "a certain way." "I can tell you that a big portion of this nation is united like it's never been united before," he said, per CNN.

2. No one will believe the Mueller report: Trump suggested Deputy Attorney General Rod Rosenstein and Special Counsel Robert Mueller have no credibility because both men "didn't get any votes." He suggested Mueller's eventual conclusion on the Trump campaign's potential involvement with Russian election interference will be seen as illegitimate, especially if it threatens his presidency. "People will not stand for it," he said, per The Hill.

3. He didn't start the McCain drama: Trump bristled when Bartiromo asked about his latest attacks on the late senator John McCain, claiming he didn't start the latest cycle of the feud. Since McCain is obviously not to blame for this week's drama, Trump pinned it on members of the media like Bartiromo, calling her "fake news." "You shouldn't have brought that up," he fumed, per Mediaite, though she pointed out she was only asking because of Trump's unprompted tweet condemning McCain.

4. The economy is not slowing: "The world is slowing, but we're not slowing," Trump insisted, simultaneously blaming the Federal Reserve for keeping growth below 4 percent last year. The U.S. economy grew last year, but at a slowing rate, reports The Washington Post. Trump said he "hope[s]" he didn't influence the Fed's decision to halt rate hikes this year, "but it doesn't matter, I don't care if I influenced them or not."

Two 2020 Democrats may have just scored — literally — the most crucial endorsement of the race: they've got the backing of Parks and Recreation's Leslie Knope.

This, at least, is according to Amy Poehler, who on Thursday speculated about which Democrats running for president might receive the support of her beloved sitcom character. The first person to come to mind was Sen. Amy Klobuchar (D-Minn.), who Poehler called a "Midwest candidate."

Poehler also agreed with the interviewer that Knope might support South Bend Mayor Pete Buttigieg, whose "underdog status" Poehler said her character would like, although neither of them could actually remember his name; Poehler seemed to think it was "Paul." Buttigieg had the best response, tweeting, "Wait till she realizes she's talking about the Indiana Parks and Recreation Association’s 2018 Elected Official of the Year..."

Weirdly, a name that didn't come up at all was former Vice President Joe Biden, even though Leslie Knope famously had an almost unhealthy obsession with him on the show. Biden even had a cameo in a scene where Leslie meets him and nearly passes out due to excitement. Maybe Poehler didn't count him since he's not officially in the race yet — or perhaps Leslie has discovered some horrifying secret about Biden's waffle opinions. Brendan Morrow

A nine-year-old girl who is a U.S. citizen says she was "scared" and "completely by myself" while being detained at the border for more than 30 hours.

Thelma Galaxia told NBC San Diego that her two children, 9-year-old Julia Isabel Amparo Medina and 14-year-old Oscar Amparo Medina, were on Monday being driven to school from Tijuana to San Diego by her friend, who told them to walk across the border after being worried that heavy traffic would make them late to school.

But the children were reportedly then detained by U.S. Customs and Border Protection and not reunited with their mother for more than 30 hours. Galaxia says officers told her daughter she didn't look like her passport picture, which was taken when she was younger. They reportedly accused her of lying about her identity and told her she would be released to her mother if she told them she was really her cousin.

Galaxia also says officers made her son sign a document identifying his sister as his cousin. "He was told that he would be taken to jail and they were going to charge him for human trafficking and sex trafficking," she said. The two were finally released when Galaxia called the Mexican consulate after being informed her children had been detained.

U.S. Customs and Border Protection officials told NBC San Diego that the young girl gave them "inconsistent info" and that they detained her so they could "perform due diligence in confirming her identity and citizenship," but they did not explain why this took more than a full day.

President Trump is closing out his workweek with — you guessed it — another attack on late Sen. John McCain (R-Ariz.).

Trump in an interview with Fox Business that aired Friday was asked by host Maria Bartiromo about his recent attacks on the Arizona senator, who died of brain cancer last year. "John McCain is dead," Bartiromo said. "Why are you doing this?" Trump used this as an opportunity to tear into McCain once again, saying he gave Christopher Steele's Russia dossier to the FBI for "very evil purposes" and that he "was horrible" for his vote against repealing the Affordable Care Act.

"I'm not a fan," Trump said of McCain.

Trump also insisted, though, that he's not the one bringing up the subject of McCain, saying, "I don't talk about it. People ask me the question. ... You people bring it up. I don't bring it up."

This is despite the fact that Trump originally began attacking McCain on Twitter, going after him in a tweet on Saturday and then again on Sunday, also retweeting a follower who said, "We hated McCain." This is what prompted questions from reporters. Trump also brought up McCain on his own during a speech on Wednesday, during which he went on an anti-McCain rant for several minutes.

Even if Trump were only talking about McCain when asked, though, he could always simply decline to answer these questions, a fact Trump acknowledged during this Friday interview. "I could say 'no comment,'" he said, "but that's not me." Watch Trump's latest exchange about McCain below. Brendan Morrow

Maverick is more than just Charlie's best friend — he's also his "seeing-eye" puppy.

Charlie and Maverick are golden retrievers, both owned by Adam and Chelsea Stipe of Mooresville, North Carolina. Charlie is almost 11 years old, and due to glaucoma, had his left eye removed in 2016 and his right in 2017. He still loves to play and go on walks but sometimes needs a little bit of help getting around. That's where Maverick comes in.

Maverick joined the Stipe family in January. Now four months old, Maverick walks next to Charlie, guiding him where he needs to go. Chelsea Stipe told NBC Philadelphia Maverick also noticed when Charlie would lose track of a toy, and would "pick it up and put it back in front of him to re-engage playtime." It took Charlie a bit of time to get used to Maverick, but now, they're inseparable. "They're both pretty crazy and special," Chelsea Stipe said. "They're definitely our entertainment."

At 94 years and 172 days old, Jimmy Carter is now the longest-living U.S. president.

Carter, the 39th president, was born on Oct. 1, 1924. When George H.W. Bush died in November, he was 94 years and 171 days old. Carter was also the first American president born in a hospital.

In office for one term, he has spent the last several decades dedicated to service, building houses with Habitat for Humanity and launching the nonpartisan and nonprofit Carter Center, which focuses on public policy. In 2002, he received the Nobel Prize. Carter announced in 2015 that he had cancer, which started in his liver and spread; he underwent surgery, and is now cancer-free.

Deanna Congileo, a representative of the Carter Center, told NBC News the organization is "grateful" for Carter's "long life of service that has benefited millions of the world's poorest people." Catherine Garcia
