On Thursday, all living presidents and spouses attended Jimmy Carter's funeral, except Michelle Obama. Here's why.

"Former First Lady Michelle Obama is not in attendance at President Carter’s National Funeral Service,” Michelle's rep Crystal Carson added to People. “Mrs. Obama sends her thoughts and prayers to the Carter family, and everyone who loved and learned from the remarkable former president."

Former President Barack Obama attended Jimmy Carter’s state funeral on Thursday without his wife, Michelle Obama, although a spokeswoman for the former first lady said she sent her condolences to the Carter family.
