WASHINGTON (AP) — Defense Secretary Lloyd Austin has ordered hundreds of Pentagon advisory board members to resign this month as part of a broad review of the panels, essentially purging several dozen who were appointed last-minute under the Trump administration. During the last two months of his tenure, former acting Defense Secretary Christopher Miller removed a number of longtime members from several defense policy, health, science and business boards and replaced many with loyalists of former President Donald Trump. More than 30 of those replacements will now be forced to resign, including former House Speaker Newt Gingrich, retired Brig. Gen. Anthony Tata and former Trump campaign manager Corey Lewandowski.
