Trumpworld is abuzz with speculation about which close aide or aides has "flipped" and provided additional sensitive information to the FBI about what former President Trump was keeping at Mar-a-Lago, sources tell Axios.

Why it matters: Trump's orbit is always an environment rife with mistrust and paranoia. Now, that's intensified.

Catch up quick: Monday's search revolves around the handling of government records — and whether Trump has been honest with federal officials.

• In a detail that seems too novelistic to be true, a focal point of the search was ... the Mar-a-Lago basement.

Christina Bobb, a lawyer for Trump, told The Washington Post his lawyers held discussions with the Justice Department this spring over materials held at Mar-a-Lago.

• Bobb said Trump's legal team searched through two to three dozen boxes in a basement storage area, hunting for documents that could be considered presidential records, and turned over several items.
• Bobb told The Post that in June, Trump lawyers showed DOJ investigators the boxes, and they looked through the material.
  • She said the investigators didn't think the storage unit was properly secured. So Trump officials added a lock.

• FBI agents broke through that lock during the search, Bobb said.

  • The FBI removed about a dozen boxes that had been stored in the basement storage area, she said.
