The Presidential Advisory Council on HIV/AIDS (PACHA) advises the White House and the Secretary of Health and Human Services on the US government's response to the AIDS epidemic. The commission was formed by President Bill Clinton in 1995 and each president since has renewed the council's charter. Six members resigned in protest of President Donald Trump's health policies in June 2017, and the remaining ten members were dismissed by Trump on 28 December 2017. While PACHA did not meet in 2018, it was restaffed in 2019 and reconvened in March, June, and October 2019.
