A cadre of former FDA commissioners under Republican and Democratic presidents say that President Donald Trump has undermined the credibility of the FDA.Robert Califf, Scott Gottlieb, Margaret Hamburg, Jane Henney, David Kessler, Mark McClellan and Andy von Eschenbach pinned a joint op-ed in the Washington Post on Tuesday.Among the group who signed the letter, Gottlieb was Trump’s longest service FDA commissioner, heading the agency for nearly two years until April 5, 2019.The former commissioners said Trump has inserted himself into the vaccine approval process.“But a safe and effective vaccine will not be enough; people will also have to choose to take it,” the former commissioners wrote. “This depends on widespread confidence that the vaccine approval was based on sound science and not politics. If the White House takes the unprecedented step of trying to tip the scales on how safety and benefits will be judged, the impact on public trust will render an effective vaccine much less so.”Last week, Trump said it’s possible he would overrule the FDA if the agency uses stricter guidelines to give an emergency use authorization for a coronavirus vaccine candidate.The group of former commissioners blasted Trump for his comments.“The implications of the recent shift are potentially dire,” they wrote. “When the FDA warns about a risk from contaminated food, will people heed it? When a new drug for cancer or heart disease is approved, will clinicians and families trust it to work? And most urgent for today: When the FDA approves a COVID-19 vaccine, will Americans accept it?”Trump has been at odds with many government public health experts on the timing of when a vaccine would be available to the public.There are several vaccines in Phase 3 testing. Even though a vaccine could be approved by year’s end, trials will be expected to continue for over a year to monitor for possible side effects.According to the FDA, a typical Phase 3 trial would take one to three years. 2000

A John Wayne exhibit in the main hall of USC’s School of Cinematic Arts will be removed. The decision comes after renewed visibility of some of the actor’s comments, and recent conversations about removing statues and memorials of those who promoted hateful views."Conversations about systemic racism in our cultural institutions along with the recent global, civil uprising by the Black Lives Matter Movement require that we consider the role our School can play as a change maker in promoting antiracist cultural values and experiences," Assistant Dean of Diversity and Inclusion Evan Hughes said in a statement.While the statement from the University of Southern California did not directly mention it, Wayne’s legacy has been re-examined recently after a 1971 interview with Playboy went viral last year. In the interview, Wayne shared derogatory views of African Americans, Native Americans and films with gay characters."I believe in white supremacy until the blacks are educated to a point of responsibility," the actor said during the 1971 interview. "I don't believe in giving authority and positions of leadership and judgment to irresponsible people."When the interview was widely shared last year, many USC students and others called for the school to remove the Wayne exhibit, according to USC student news outlet Annenberg Media. 1351

A Houston police officer was killed Tuesday and a second officer was injured on Tuesday morning in what Police Chief Ralph Acevedo called a "domestic violence-type situation."The officer killed was Officer Harold Preston, 65, a 41-year-old police veteran. Acevedo described Preston as a great cop "and a better person."According to Acevedo, officers were called to a home in the city's southwest side of the city by a woman who described herself as the estranged wife of the man who lived there. She said she was moving out and needed to collect her belongings, but her husband wouldn't let her in the house.When police approached the door, the suspect allegedly fired at the officers. Preston was shot multiple times in the head. A second officer, Officer Cortney Waller, was shot in the shoulder and is expected to survive.Several hours after police first arrived, the suspect emerged from the house and exchanged gunfire with police. The suspect, idnetified as Elmer Manzano, 51, was transported to the hospital and is expected to survive. Acevedo said Manzano will likely be charged with murder.Manzano's son was also injured in the incident and was transported to a local children's hospital with non-life-threatening injuries.KTRK-TV in Houston reports that Tuesday's shooting comes days after a Houston Fire Department Arson Investigator was shot and killed while doing surveillance in the northwest side of the city. 1432
