Ivanka Trump can't recall key details of the single biggest fraud-trial penalty threat her father faces

• At her family's civil fraud trial, Ivanka Trump was grilled about the 2011 Old Post Office lease.
• She repeatedly told a state attorney she could not remember key details, despite helming the deal.
• The Trumps made $139M off the deal, and the NY attorney general seeks a big cut, as a fraud penalty.

In afternoon testimony at her family's civil fraud trial in Manhattan, Ivanka Trump repeatedly said she could not remember key details about the single, costliest penalty threat her father faces in the case.

That threat — totaling tens of millions of dollars in potential penalties — concerns the family's federal Old Post Office lease deal in Washington, D.C.
