A Department of Homeland Security official and presidential appointee will leave his post after scaling back on some counterterrorism efforts involving weapons of mass destruction.
James F. McDonnell, who led the Countering Weapons of Mass Destruction Office, will step down at noon Thursday, The Los Angeles Times reports .
Acting Homeland Security Secretary Kevin McAleenan requested McDonnell’s departure.
In his seven-sentence resignation memo, McDonnell did not give a reason for resigning.
McDonnell has faced criticism earlier this year for promoting a scientifically-disputed system for detection of airborne infectious agents such as anthrax.
McDonnell also directed “the scaling back or elimination of multiple anti-terrorism programs at Homeland Security, which has primary domestic responsibility for helping authorities detect and block WMD-related threats,” The Los Angeles Times wrote.
