Twitter CEO Jack Dorsey says "we're ready to question everything" about the social networking site that has been overrun by spam, abuse and misinformation.Dorsey says he and his team are working extensively behind the scenes to stamp out some of the harassment and hate speech that has generated bad headlines lately.But it is a long-term effort, he says, and he is reluctant to commit to an exact timetable for certain changes to Twitter's foundation.In twelve years, "we've changed a lot. But we haven't changed the underlying fundamentals," Dorsey told CNN in an in-depth interview at the company's headquarters on Friday.The basic fundamentals are what he is examining now. For instance: What does Twitter incentivize its users to do?"Every product decision we make is 'telling' them to do something," Dorsey said.So he is thinking about how to help users follow topics and hashtags, not just people."We are aware of some of the silos and how we're isolating people by only giving them crude tools to follow accounts. We need to broaden our thinking and get more back to an interest-based network," he said.Related: Twitter's Jack Dorsey: 'We are not' discriminating against any political viewpointDorsey is also rethinking how follower counts and "likes" on posts are displayed, because the race to gain followers and likes may encourage outrageous behavior.His view is that Twitter needs to be much more "transparent" and open about its actions. But that transparency, some of which was on display during Dorsey's media tour this month, means asking questions without actually answering them.Among the questions Dorsey asked in the CNN interview: "How do we earn peoples' trust?" and "How do we guide people back to healthy conversation?"While he may get credit for asking big, philosophical questions about how his site operates, Dorsey remains vulnerable to criticism about Twitter's inaction.He responded to that by saying "we are taking a lot more action than we ever have in the past." But much of the action is invisible to users, he asserted.For example: The disabling of bot networks and other suspicious accounts. Dorsey said Twitter challenges "10 million accounts every single week to see if they're automations or humans," and takes action accordingly.But Twitter's stock plunged last month when its quarterly earnings report showed a decline in user growth, which the company attributed to its efforts to clean up the site, akin to gardeners removing weeds.Nonetheless, Dorsey is committed to what he calls "conversational health" -- the quality of an exchange on Twitter -- which he is trying to measure with the help of two research groups. He said investors should take a look at the long-term trends: "We see this as necessary and right and we believe in it and we have conviction around it, and we'll take the hit in the short term."Related: Twitter is purging suspicious accounts from your follower countHe also asserted that "over the short term, a lot of this work is invisible, and over the long term, it starts to add up."As for some of the specific changes, like a rethinking of the like button, Dorsey was reluctant to talk about a timeline."We're looking and thinking about all these things right now," he said. So: By the end of the year? "I worry about a time frame like that," he said, "because we also need to take into consideration -- we're a small company. I mean we, in comparison with our peers, we're a small company, but we have this outsized impact and I believe, importance."Later, he added, "We have to understand first the problem we're trying to solve, like what incentives we actually want to drive; not just what we want to remove, but what we want to drive." But he said he knows he wants incentives "that encourage people to talk and to have healthy conversation." 3824

TUCSON, Arizona — Another U.S. Senate seat will soon be up for grabs in Arizona.Governor Doug Ducey announced Friday morning that Senator Jon Kyl — who Ducey appointed to the Senate after John McCain's death in August — will step down from his role at the end of the year.That leaves Ducey in the hot seat — he'll have to appoint another Senator to fill the seat until a special election can be conducted in 2020. By Arizona law, Ducey — a Republican — has to appoint someone of his same political party.Ducey hasn't offered any insight into who he would appoint, but speculation included several prominent Republican names, including McCain's widow Cindy McCain and former Senate candidate and Congresswoman Martha McSally. 742

VALLEY CENTER, Calif. (KGTV) - The 12-year-old survivor of a plane crash in Valley Center is praising her uncle, the pilot who died in the crash.A smiling photo of Raquel Contreras was taken moments before her uncle, Peter Bierle, a seasoned pilot, took her up in his single-engine, experimental aircraft on an early Sunday evening. They were above the home of her friend for a birthday flyover when it happened. More than two weeks after the crash, Contreras spoke to us from her hospital room. She says some neighbors got an early warning."The plane hadn't even crashed, and they were getting ready because they heard engine failure," said Contreras.RELATED: Pilot killed, 12-year-old girl badly injured in small plane crash in Valley CenterA traumatized Contreras didn't want to talk about the crash, but her family says her uncle told her to, "Get down low and hold on."Witnesses saw the plane dive toward the yard, away from buildings, before it crashed."I want to honor Uncle Peter. It's amazing what he did, and I wouldn't be here if he didn't land and crash like he did," said Contreras.Bierle died at the scene. Dozens of neighbors rushed to the plane, burning fuel nearby."Just want to thank everyone on Palomar Vista Drive ... Amazing how everyone came together in the end," Contreras said.Contreras was cut out of seat belt and rescued. That seat belt was a 4-point harness belt, courtesy of her Aunt Connie."Right before the flight, she put in a new seat belt and checked my buckle," says Contreras.The last-minute addition may have saved her life. Raquel was hurt badly, with injuries to her eye and spine, and fractures to her skull, sternum, and hand.Two surgeries later, a determined Contreras is now beginning her long road to recovery."We've just been taking steps slowly and steadily," she said.A Gofundme campaign has been set up to help the family with expenses.The NTSB has yet to release its initial findings on the crash. 1954

TUCSON, Ariz. — With hospitals at capacity due to a surge in COVID-19 cases, an Arizona woman says her mother had to wait 13 hours in bed in a hallway while waiting for a room to open up.Sam Bero said her mother went to St. Joseph’s Hospital in Tempe last week after delaying care for an infection earlier this year.Bero said her mother's illness went from infection to kidney stones, and eventually turned into a larger medical issue.“It just ended up turning into a bigger problem than it should've been,” she said.The Center for Disease Control released a report in June that estimated that 41% of U.S. adults had avoided medical care because of COVID-19 concerns — included 12% who reported having avoided urgent or emergency care.Bero said her mother got to the hospital at 1 p.m. and wasn't given a room until 2:45 a.m.“They were triaging patients in the waiting room, so doing all the blood pressure, IVs and all in the waiting room,” Bero said. “And then, when she finally did get a bed, she was in a bed in the hallway for 13 hours.”On Tuesday, the Arizona Department of Health Services (ADHS) reported that there are 192 ICU beds available across Arizona and 1,093 inpatient beds available. ADHS is reported the highest number of inpatient COVID-19 patients in this new surge, with 2,084 people in their hospital metrics.COVID-19 patients in ICUs also are climbing with 474 people hospitalized — a similar number we saw right before a surge in cases this summer.Hospital leaders across Arizona say that the number of available beds can change throughout the day as the number of patients goes can change.A spokesperson for Carondelet Health Network — the company that operates St. Joseph's — said that while their hospitals continue to have the capacity to treat patients needing medical care, “like any hospital, the number of patients in-house can fluctuate daily.”Hospitals across Arizona are working to secure more staffing, as there is expected to be an increase in hospitalizations from COVID-19 in the coming weeks.“We commend our team of health care professionals who are working valiantly to ensure our preparedness as we continue caring for our community,” the Carondelet spokesperson said.Bero said her mother has since been released from the hospital, and she’s expected to be okay.“The poor nurses and doctors are so overworked,” she said.This story was originally published by Nicole Grigg on KNXV in Phoenix. 2441
