In October 2015, Weinstein sent a letter to Lt. Col. Don Tasker, the commanding officer of the 436th Force Support Squadron at Dover Air Force Base, to report that one of Tasker's subordinates was illegally using her official government email to endorse and encourage participation in Operation Christmas Child, an annual charitable event created and led by Samaritan's Purse that explicitly endorses the Christian faith and encourages evangelization for that faith. Shortly after receipt of this letter, Tasker disavowed the email and stated, "I want to be absolutely clear that the email in question was not sent at my direction and is not endorsed in any way by me or any level of command."
