While Nikki Haley's appearance on "Army Wives" was mired in controversy, Jill Biden's cameo didn't draw half as much attention. The first lady appears in Season 4, Episode 16, "Mud, Sweat and Tears," which was filmed when her husband, President Joe Biden, was Barack Obama's vice president. She acts as the grand marshall for a fun run being held by the main characters, who are hoping to raise money for military mothers without further funds to help themselves. "I'm proud to be here today as a second lady, but I'm even more proud to be here as a military mom," she declares during her appearance. The episode is unique for featuring a large number of real-life military wives during the fun run segment.
If that isn't enough of a connection to the real-life political and military goings-on, "Army Wives" was based on the book "Army Wives: The Unwritten Code of Military Marriage," which contains the stories of actual military wives as collected by Tanya Biank. That's quite the commitment to grounding all that drama in the real world.
