Gina Haspel on Friday sought to withdraw her nomination as President Donald Trump's pick to head the CIA after some White House officials raised concerns that her role in the agency's interrogation program could sink her confirmation, according to The Washington Post.During a Friday meeting at the White House, Haspel, the current CIA deputy director, signaled she would step aside to avoid potential damage to her and the agency's reputations, The Post reported Sunday, citing four senior US officials.Haspel, a 33-year CIA veteran, was summoned to the White House to answer questions about her role in the agency's controversial interrogation program, the Post reported.Haspel feared becoming "the next Ronny Jackson," the former White House physician who withdrew his nomination as Veterans Affairs secretary amid questions about alleged misconduct on the job, one official told the Post.After Haspel left the meeting, senior White House officials, including press secretary Sarah Sanders and legislative affairs director Marc Short, rushed to CIA headquarters Friday afternoon to meet with Haspel at her office, The Post reported.The newspaper said Trump learned of the situation on Friday and called officials while in Dallas for the National Rifle Association convention. After initially signaling he would support whatever decision was taken, Trump decided to push for Haspel to remain the nominee, according to the newspaper.By Saturday, Haspel had agreed to continue with her nomination, officials told the Post.Both Short and Sanders declined to comment to the Post about Haspel's offer to withdraw."There is no one more qualified to be the first woman to lead the CIA than 30+ year CIA veteran Gina Haspel," Sanders wrote on Twitter Saturday. "Any Democrat who claims to support women's empowerment and our national security but opposes her nomination is a total hypocrite."Two potential sticking points in Haspel's nomination are her past oversight of a CIA "black site" in Thailand in 2002 and her involvement in the destruction of CIA videotapes showing the waterboarding of terrorism suspects in 2005, although the CIA released an internal review last month absolving Haspel of responsibility.The official who conducted the review, former acting CIA Director Michael Morell, told CNN that Haspel had merely drafted a cable under instruction from her boss, former clandestine chief Jose Rodriguez, "that he sent, under his name and authority, ordering that the tapes be destroyed."A CIA spokesperson told CNN on Sunday, "There has been a fascinating phenomenon over the last few weeks. Those who know the true Gina Haspel -- who worked with her, who served with her, who helped her confront terrorism, Russia and countless other threats to our nation -- they almost uniformly support her.""When the American people finally have a chance to see the true Gina Haspel on Wednesday, they will understand why she is so admired and why she is and will be a great leader for this Agency," the spokesperson said.Haspel faces a Senate confirmation hearing Wednesday. Her nomination would be in jeopardy only if she loses the support of Republicans, who hold a slim 51-49 seat majority in the Senate. 3213

HAMPTON ROADS, Va. - As coronavirus continues to rage across the country, scientists are inching closer to developing a COVID-19 vaccine.Dr. Doug Mitchell used to be a pediatric infectious diseases specialist at CHKD and EVMS. He is currently the medical director of CHKD Medical Group and a pediatrician at Norfolk Pediatrics.“If we’re able to stick to the science in developing the vaccine, then that would be comforting if we could stick to the science and develop an effective and safe vaccine,” said Mitchell.Mitchell said the speed at which researchers are developing a vaccine to combat COVID-19 is nothing short of a miracle, but sticking to the clinical science behind the advancement is key for an effective and safe vaccine - and that takes time.“The stated goal that I saw by the CDC and/or FDA of wanting a vaccine that shows at least 50% protection and six months of safety data, that takes time,” he said. “We need a chance to show the safety profile of any new vaccine under the parameters of following the best science that we could follow.”Mitchell understands the process involved in developing a vaccine.More than 20 years ago, he was an investigator in several pediatric clinical trials. Many of the vaccines that came out of his lab are still used in children today.While there are still growing concerns about vaccines, the benefits outweigh the risks.“The flu vaccine clearly saves lives, clearly prevents illnesses, but it’s not 100% protective either, but we know it does have benefits,” Mitchell said. “The advantage there is the flu vaccine has been out for decades and we know its safety profile.”Similar to the rapid speed of developing a COVID-19 vaccine, Mitchell said a vaccine for H1N1, better known as the swine flu, was quickly put on the market.“The difference is, we already had decades of history of flu vaccines and their safety, so all that happened was developing the same flu vaccine that was protective against a different strain,” he said. “That’s a different ballgame than starting a vaccine against a totally different virus.”While the research continues, the fight against COVID-19 is far from over.According to Mitchell, the spread of the virus decreases when you reach heard immunity where enough of the population is immune.This story was first reported by Antoinette DelBel at WTKR in Norfolk, Virginia. 2363
