Six top health advisors have resigned from Donald Trump’s advisory council on HIV/AIDS, complaining that the US president doesn’t really care about combating the illness.

In a letter published in Newsweek on Friday, Scott Schoettes counsel and HIV project director at Lambda Legal said, the Trump administration has no strategy on AIDS and that he and his five colleagues will be more effective advocating for change from the outside.

Schoettes, resigned Tuesday from the Presidential Advisory Council on HIV/AIDS, along with Lucy Bradley-Springer, Gina Brown, Ulysses Burley III, Michelle Ogle and Grissel Granados.
