Biden says "there's no there there" on classified documents. Here's what that means.

While answering questions on his handling of classified documents, President Biden told reporters on Thursday: "There's no there there." But what does the saying mean?

The phrase originates from author Gertrude Stein's 1937 autobiography, "Everybody's Autobiography." Describing her childhood home, Stein wrote:

"...what was the use of my having come from Oakland it was not natural to have come from there yes write about it if I like or anything if I like but not there, there is no there there."
