WASHINGTON (AP) — The Pentagon has stopped calling the deployment of troops to the U.S.-Mexico border "Operation Faithful Patriot," dropping the name even as thousands of American forces head to southern Texas, Arizona and California.According to U.S. officials, Defense Secretary Jim Mattis directed the department to stop using the name and simply describe the mission as military operations on the border. The change was ordered early this week, but no reason was given.Lt. Col. Jamie Davis, a Pentagon spokesman, would only say that the department is no longer using the name. But other U.S. officials said Mattis didn't like the name and believed it was distracting from the troops' actual mission, which is in support of the border patrol. The officials spoke on condition of anonymity to describe internal deliberations.The name hasn't been formally changed or rescinded, but the Pentagon has stopped using it in press releases and documents.Pentagon officials rolled out the name last month after President Donald Trump ordered thousands of active duty troops to the southwest border in response to a caravan of migrant families walking slowly north through Mexico toward the U.S.As of Wednesday, more than 5,600 troops have been deployed to Texas, Arizona and California and are mainly in staging bases. Only about 500 troops are actively supporting operations on the border, and many of those have been installing coils of razor wire and erecting tents to house U.S. troops and border patrol.The military says it will deploy a total of about 7,000 troops, but has left open the possibility that the number could grow. Last week, Trump said he would send as many as 15,000 troops. There also have been about 2,100 National Guard troops operating along the border for months as part of a separate but related mission.The Pentagon still has refused to release any cost estimates for the troop deployment.The name adjustment was first reported by The Wall Street Journal. Meanwhile in Mexico, the caravan is weighing whether or not to stay in the country or continue their journey to the U.S. Mexico City officials said they expected as many as 1,000 more might arrive at the Jesus Martinez stadium as lagging members of the caravan trail in, their journeys slowed by difficulties in getting rides or by hopping aboard trucks that veered off their route.Angel Eduardo Cubas of La Ceiba, Honduras, reached the shelter early Wednesday after being split off from the caravan. Like many migrants he had to find his way back to the relative safety of the caravan in an unfamiliar country, with no money."There were a lot of people who got dropped off somewhere else," said Cubas, who at one point lost his two children, 2 and 6, before finding them again. "It was ugly, going around looking" for his kids, the 28-year-old father said.Members of the caravans of migrants, which President Donald Trump made a central issue in U.S. midterm elections, declined to take an immediate decision Tuesday night on whether to stay in Mexico or continue north, opting to remain in the capital at least a couple more days."Nobody is in more of a hurry than me to get going (to the U.S. border), but we have to go all together," said Sara Rodriguez of Colon, Honduras.Rodriguez, 34, fled her country with her 16-year-old daughter Emily, after the girl began to draw unwanted attention from a drug trafficker who just got of prison and pledged to go after her. Rodriguez left her 7-year-old son with her husband in Honduras. "Even though it hurts to leave my son ... I had to protect her," Rodriguez said, weeping.Mexico has offered refuge, asylum or work visas to the migrants and the government said 2,697 temporary visas had been issued to individuals and families to cover them while they wait for the 45-day application process for a more permanent status.Rina Valenzuela, who is from El Salvador, listened attentively to aid workers from the nonprofit Institute for Women in Migration as they explained the difficulties of applying for and securing asylum in the U.S. Valenzuela decided she would better off applying for refuge in Mexico."Why go fight there, with as much effort and as much suffering as we have gone through, just for them to turn me back? Well, no," she said.Hundreds of city employees and even more volunteers helped sort donations and direct migrants toward food, water, diapers and other basics. Migrants searched through piles of donated clothes, grabbed boxes of milk for children and lined up to make quick calls home at a stand set up by the Red Cross.Employees from the capital's human rights commission registered new arrivals with biographical data— such as age and country of origin— and placed yellow bracelets on wrists to keep count of the growing crowd.Maria Yesenia Perez, 41, said there was no space in the stadium when she and her 8-year-old daughter arrived Tuesday night, so the two from Honduras slept on the grass outside. Migrants pitched tents in the parking lot and constructed makeshift shelters from plywood covered with blankets and tarps. Forty portable toilets were scattered across the grass.Several smaller groups were trailing hundreds of miles to the south; officials estimated about 7,000 in all were in the country in the caravans.Trump portrayed the caravan as a major threat, though such caravans have sprung up regularly over the years and largely passed unnoticed.Former Honduran lawmaker Bartolo Fuentes, who denies accusations he started the caravan, described it as a natural response "to a situation more terrible than war." He said about 300 to 400 Hondurans leave their country on an average day."What do we have here then? The accumulation of 20 days" of normal emigration, he said. 5757

Watching your dog get old is hard. You see the pain in their eyes when they can't get into the car or run after the ball.Veterinarians across the U.S. say it's not just old age, but arthritis that's causing your dog pain, and a new drug trial is working to make your furry companion feel better.One of the clinics testing the new drug is Paradise Animal Hospital in Catonsville, Maryland. Dr. Cheryl Burke says she to qualify for the trial, dogs have to have obvious signs of arthritis and cannot have cancer. At the clinic, they conduct blood tests, x-rays and a physical exam.Hannah, a blonde chow mix, came in for the procedure."She has a lot of trouble getting up and when she goes to walk up and down the stairs, she stares, like can I do this? Can I do this? Breaks my heart when I see that," Hannah's mom, Donna Foster said.Foster found out from a friend this clinic was conducting the trial and thought she'd take a chance, "I mean she's fourteen years old and basically she's really healthy so if I can keep her for another 20 years, I know that's not realistic but I will and I want her to have a quality of life."The trial was created in San Diego, by Animal Cell Therapies, and uses canine stem cells to grow cartilage in the joint, so the dog has more cushion when he/she walks or runs."Stem cells are the body's primitive precursor cells and we all have them, and when we're born, there's a huge population of them in our umbilical cord," Dr. Burke said.The stem cells adapt to the needs around them, so they could turn cancerous, something Dr. Burke and pet parents don't want. That's why dogs go through several tests (for free) before they can qualify.The clinic is doing the entire trial for free, to get FDA approval, so other pet parents can one day buy the drug.Part of the study requires that the test be double blind, meaning no one, even Dr. Burke can see which drug is given to the dog.Each dog undergoes the same procedure. Then pet parents come back for a one month, three month and six month check up to see how the dog is progressing.If the study is approved any dog who didn't get the drug will get it for free."If it's approved, it could be a few years, before it's on the market but it could be wonderful," Dr. Burke said.There is no ballpark figure as to how much the drug may cost, but dog lovers are hopeful it could help their furry friend have a longer, better life. 2431

WASHINGTON (AP) — President Donald Trump on Wednesday named Robert O'Brien, his chief hostage negotiator and an established figure in Republican policy circles, as his new national security adviser.O'Brien, the fourth person in two years to hold the job, becomes the administration's point person on national security amid rising tensions with Iran following the weekend attack on Saudi oil installations and fresh uncertainty in Afghanistan after the halt in peace talks with the Taliban.The announcement of O'Brien's selection comes a week after Trump ousted John Bolton from the post, citing policy disagreements. O'Brien, who made headlines in July when he was dispatched to Sweden to monitor the assault trial of American rapper A$AP Rocky, was among five candidates Trump said Tuesday were under consideration."He's worked with me for quite awhile now on hostages and we have a tremendous track record on hostages," Trump said Wednesday on a tarmac in Los Angeles, hours after revealing the pick on Twitter. "Robert has been fantastic. We know each other well.O'Brien, standing alongside Trump, said it was a "privilege" to be picked."We've had tremendous foreign policy successes under President Trump's leadership. I expect those to continue. We've got a number of challenges," he added. O'Brien said the administration's focus will continue to be on keeping the U.S. safe and rebuilding the military. He said he would advise Trump privately on the situation in Saudi Arabia.Trump abruptly forced out Bolton on Sept. 10, after he and his hawkish national security adviser found themselves in strong disagreement over the administration's approach to Iran, Afghanistan and a host of other global challenges. The sudden exit marked the latest departure of a prominent voice of dissent from Trump's inner circle as the president has grown more comfortable following his gut instinct over the studious guidance offered by his advisers.As the special presidential envoy for hostage affairs at the State Department, O'Brien worked closely with the families of American hostages and advised administration officials on hostage issues.He helped secure the release in February of American citizen Danny Burch, who was freed after 18 months in captivity in Yemen. He has also worked on the case of missing U.S. journalist Austin Tice, who was captured in Syria in 2012. O'Brien has said the U.S. is confident Tice is still alive.The White House sent O'Brien to Sweden to monitor the case of A$AP Rocky, who was charged with assault. The rapper, whose real name is Rakim Mayers, was permitted to return to Los Angeles to await the verdict of a Swedish court, which found him guilty in a street brawl.Last month, Hua Qu, the wife of a Princeton University graduate student detained in Iran, told reporters that she would like to see the same level of personal attention from the government as A$AP Rocky received.On Wednesday, a Twitter account that advocates for the release of the student, Xiyue Wang, congratulated O'Brien on the appointment but also said: "We watched with frustration as this administration put all its energies into releasing celebrity A$AP Rocky from Sweden; meanwhile, (asterisk)multiple(asterisk) Americans suffer under terrible conditions in #Iran. Let's put all Americans first, not just famous ones. #AmericansFirst."O'Brien previously helped lead the department's public-private partnership for justice reform in Afghanistan during the Bush and Obama administrations.He began to emerge as a front-runner to replace Bolton last week when it became clear that an early favorite, Iran envoy Brian Hook, would face opposition from hawks who think he has not been tough enough on Iran, according to Republicans familiar with the matter.Another short-listed candidate, the North Korea envoy, Stephen Biegun, was taken out of the mix when Secretary of State Mike Pompeo suggested he might be better placed as deputy secretary of state to replace John Sullivan, who is widely expected to be nominated to be the next U.S. ambassador to Russia, officials said.From 2008 through 2011, O'Brien was a presidentially appointed member of a government committee that advises on issues related to the trafficking of antiquities and other cultural items. In 2005, President George W. Bush nominated O'Brien to be U.S. representative to the U.N. General Assembly, where he worked with Bolton. O'Brien was confirmed by the Senate.He also was an adviser on the Republican presidential campaigns of former Gov. Scott Walker of Wisconsin, former Gov. Mitt Romney of Massachusetts and Sen. Ted Cruz of Texas.Earlier in his career, O'Brien was a senior legal officer for the U.N. Security Council commission that decided claims against Iraq that arose from the Gulf War. He was a major in the U.S. Army Reserve.O'Brien has a law degree from the University of California, Berkeley, and co-founded a law firm in Los Angeles focused on litigation and international arbitration issues. O'Brien is the author of "While America Slept," a collection of essays on U.S. national security and foreign policy billed as a "wake-up call to the American people."The book warned that the world had become more dangerous "under President Obama's lead-from-behind foreign policy."____Associated Press writer Matthew Lee contributed to this report. 5338

WASHINGTON (AP) — Zookeepers at Washington’s National Zoo are on furry black-and-white baby watch after concluding that venerable giant panda matriarch Mei Ziang is pregnant and could give birth this week. It’s a welcome bit of good news amid a pandemic that kept the zoo shuttered for months. The announcement of the pregnancy has already touched off a fresh round of panda-mania for one of the zoo’s feature attractions. “We need this! We totally need this joy,” said zoo spokeswoman Pamela Baker-Masson. “We are all in desperate need of these feel-goods.”Although so-called “phantom pregnancies” are common with pandas and other large bears, Baker-Masson said an ultrasound scan revealed a “really strong-looking, fantastic fetus” that could be delivered this week.Mei, at 22, would be the oldest giant panda to successfully give birth in the United States. The oldest in the world gave birth in China at age 23.Viewership on the zoo’s panda-cam has increased 800 percent. 984
