The second lady does not have a background in national security law, but a White House chronicler says her expertise was called on anyway.

Second Lady Usha Vance was a secret adviser on a high-stakes minerals deal with Ukraine this year, White House chronicler Jonathan Karl claims in a forthcoming book. The question of whether the February deal had been legally vetted emerged during talks between President Donald Trump and Vice President JD Vance. Karl writes that’s when the VP stepped in to offer his wife’s legal expertise. “I can have Usha take a look at it,” Vance said, according to Politico, which obtained an excerpt of Karl’s book.
