SAINT PAUL, Minn. – As college campuses around the country reopen, more than 200 student-run EMS programs are bracing for the inevitable surge in on-campus COVID-19 cases.“I don’t think it will fully hit me until we gear up and I am headed out to that first call,” said Hannah Gilbert.Gilbert is co-president of the student-run EMS program at Macalester College in Minnesota. The school is allowing some students to return to campus, mostly first-year international students, while the rest of the student body will start the semester with online classes. Later in the semester, Macalester may slowly transition more classes to in-person, depending on the containment of COVID-19.With the expectation of, at least, some student returning to campus, MAC-EMS is preparing for the possible surge in COVID-19 cases by, first, increasing service from two days a week to seven days a week this semester.“We need to put the work in so that we are prepared for every situation we can imagine, and we have to be ready to adapt to every situation we can’t imagine,” said Gilbert.The college is also stockpiling PPE gear for the student EMTs, while Gilbert is leading refresher courses in providing oxygen, opening airways, and even responding to a cardiac arrest situation, since those are the most troubling symptoms connected with COVID-19.“It is definitely something that is different because we don’t normally see a lot of respiratory situations, that is not the normal patient load,” said Macalester College Student EMT Kate Seeger.New COVID-19-related protocols have also been written into the student EMT handbook. The biggest change is, when possible, EMTs will now start a call with a virtual screening.“We are actually going to be zooming them, or facetiming or Skyping them from outside their room,” said Gilbert.The goal with virtual screenings is to determine their risk of exposure to COVID-19 and what PPE gear is needed to provide service safely. However, the hope is that all this training and preparations isn’t as necessary as some experts suggest.“We wish we could be on the frontlines of prevention, and we are definitely going to be out there trying to be good role models for our peers, but at the same time instinctively and intrinsically we are the ones who show up when there is an emergency,” said Gilbert. “A lot has to go wrong before you get to that emergency, so you can’t just rely on us.”Student EMTs at Macalester College, and at other colleges around the country, are relying on their classmates to adhere to social distancing guidelines and other safety protocols so they can now help on the frontlines without being overwhelmed. 2663

Sam Nunberg's interview tour is over for now.Nunberg was booked to appear on CNN's "New Day" on Tuesday morning, but he did not show up for the interview.When an unknown person answered the phone at his home Tuesday morning, the person said Nunberg is done doing interviews.According to two sources with knowledge of the matter, ABC also pursued Nunberg for Tuesday's "Good Morning America." But the producers feared that he would bail, and sure enough, he stopped responding to messages on Tuesday morning. "He went dark," one of the sources said. Nunberg's change in media strategy appears related to the change of heart that unfolded before a national audience during his media tour on Monday.The former Donald Trump campaign aide gave more than a dozen interviews on Monday in an extraordinary act of defiance of special counsel Robert Mueller.Related: Who is Sam Nunberg?He started out by flaunting Mueller's subpoena and saying "let him arrest me." At one point, he even handed the subpoena paper to MSNBC anchor Ari Melber. He seemed to revel in the show he was starring in."Jake, I'm definitely the first person to ever do this, right?" he asked CNN's Jake Tapper.Interviewer after interviewer emphasized that Nunberg could be facing serious legal jeopardy. They asked if he wanted to reconsider his position; asked if he'd consulted his lawyer; and asked about his family.Nunberg asked questions too -- almost as if he was seeking legal advice. In the 7 p.m. hour on Monday, he asked CNN's Erin Burnett, "Do you think Robert Mueller is going to send me to prison, Erin, for this?" She answered, "I don't know, but he certainly would be within his rights."Some of Nunberg's associates said they were worried about his state of mind. Burnett said at the end of the interview that she smelled alcohol on his breath. But he denied that he had been drinking.Paparazzi-style photographers were waiting for Nunberg outside CNN's New York bureau. He spoke with one of the camera crews and then continued talking with reporters by phone. But his tone changed. By the end of the day, Nunberg signaled that he will continue cooperating with Mueller, after all.The special counsel office had no comment.Nunberg's last interview of the day appeared to be with Olivia Nuzzi of New York magazine. He told her around midnight that "I'm gonna cooperate!"Regarding his TV tour, he said to Nuzzi, "Did I sound drunk? I think that I was just more of myself in these interviews than I've ever been. That's what I think it was."He took another call, then called Nuzzi back at 12:55 a.m., said he was happy that "I didn't get dumped by my lawyer today."On Tuesday morning, Nunberg did not answer calls to his cell phone. Callers were greeted by a message that said, "The voice mail belonging to Sam Nunberg is full."The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company. All rights reserved. 2906

SAN DIEGO — The Saturday after Thanksgiving is normally one when small businesses take center stage, but the Coronavirus has changed everything."We've been in North Park for eight and a half years, and we'd like to try to make it to nine," said Gail Higgins, who owns The Girl Can't Help It vintage shop on Grim Avenue. Higgins says in-store sales are now at about 30 percent, as foot traffic declined amid the pandemic."We give out gloves, if people want to try things on, we make sure everyone has a mask on, we keep the door locked so we can let in a certain amount of people at a time," she said. Normally the Saturday after Thanksgiving - called Small Business Saturday - is one that helps boost sales for mom and pops, with all sorts of pomp and circumstance to welcome the public. This year, the live music, and refreshments that typically line main streets aren't happening."If we want North Park and communities like North Park to be around next year, we have to pull it out this year," said Angela Landsberg, who heads the North Park MaiN Street Association. "We have to come on out to our local shops, shop online and support these small businesses. Keep it local."The association is now helping local retailers beef up their online presence, launching a shop local campaign with an online directory on its webpage, Explore North Park.At North Park's ArtElexia, which specializes in Mexican gifts, art, home decor and gourmet foods, owner Elexia de la Parra says her increased online presence could help for the future."Now when all this comes back to normal, I'll have a really get website," she said. "You just got to keep positive."In that light, Higgins says she has something for any occasion."Come on everybody, get dressed up at home, get dressed up for your next Zoom meeting," she said. "We can find you something for the top half."Something maybe to be found this Small Business Saturday. 1917

  

SAN DIEGO (CNS and KGTV) - The San Diego Humane Society announced Thursday that its Humane Law Enforcement division conducted a one-day sweep of pet stores and issued more than 100 citations for violations of a partial state ban on the sale of dogs, cats and rabbits.Assembly Bill 485, which went into effect at the beginning of this year, requires pet stores to get their animals from a partnered shelter or rescue center in an effort to curb the sale of pets from so-called puppy mills and kitten factories that breed animals for sale en masse, often in inhumane conditions.Humane Law Enforcement officers issued 39 citations to Broadway Puppies and 38 to Bark Avenue, both located in Escondido, for failing to provide a documented agreement with a public or private animal shelter or rescue organization, according to Humane Society spokeswoman Dariel Walker. Officers also issued 25 citations to Pups & Pets in Santee for improper signage on the cages holding its available animals, she said.RELATED: 26-pound cat helping raise awareness on pet obesity10News spoke to Mindy Patterson, Co-President of "The Cavalry Group," an organization that represents animal businesses. One of their members is Broadway Puppies in Escondido. Patterson said AB485 treats legitimate pet stores unfairly."To mandate that a store is required to obtain and source their animals for sale, from a specific source is unconstitutional," Patterson said. "All I know is that our members are in accordance with the law."Patterson said she wants the public to recognize the difference between illegitimate backyard breeders and USDA-certified breeders. She said both of them are often lumped into the same negative category of "puppy mills.""They are licensed, regulated and regularly inspected facilities that meet very stringent standards," Patterson said. Cavalry Group co-founder Mark Patterson said the store "and its parent organization are faithfully following the letter of the law in this case and will be exonerated of these citations. Other pet stores in San Diego County have been subject to similar harassment by SDHS only to have the citations dismissed in court."Representatives of the other two pet stores could not immediately be reached for comment on the citations, which were issued during a countywide sweep Wednesday of pet stores under the Humane Society's purview.Last July, the county's Department of Animal Services ceded nearly all countywide animal control duties to the Humane Society, except unincorporated areas of the county that are served by the department's shelters in Carlsbad and Bonita.RELATED: San Diego Humane Society sees surge in young wildlife in need of care"My advice is beware," said Humane Law Enforcement Officer Allen Villasenor. "As a brand-new law takes effect, people will use different methods to try to circumvent the law and at this point it's our job to make sure everything is in compliance. I always suggest looking into shelters first, go to the adoption agencies first and see if you can find the right fit for your family there."Residents can report possible violations of the state pet sale laws by calling the Humane Society's Law Enforcement division at 619-299-7012. 3221

  

SAN BERNARDINO, Calif. (AP) — Searchers are combing a section of the San Bernardino Mountains for signs of a missing off-duty firefighter. The San Bernardino County Sheriff's Department says the search Saturday is focusing on an area of Highway 18 where Carlos Baltazar’s car was located by the California Highway Patrol on Sept. 20. Baltazar is a member of a U.S. Forest Service Interagency Hotshot Crew. He was reported missing by family members on Sept. 24. At the time, he was off duty and not in the area of the El Dorado Fire in the San Bernardino National Forest. Another hotshot, Charles Morton, died while fighting that fire on Sept. 17. 654
