First Lady Michelle Obama on Tuesday described living in the White House as like being in a “really nice prison.”

Obama’s comment came during her discussion with former First Lady Laura Bush at the African First Ladies Summit in Tanzania during an interview moderated by journalist Cokie Roberts.

Roberts noted that Martha Washington, the first First Lady, also described living in the role as akin to being a state prisoner.

Obama said she loved her job and found it liberating in some respects, but confining in others.

“There are some prison elements to it,” she joked. “But it’s a really nice prison.”

Former first lady Laura Bush reminded the crowd that First Ladies had a chef.

“You can’t complain,” Michelle Obama admitted. “But there is definitely elements that are confining.”
