“That we know of” is a hefty disclaimer when it comes to the Trumps. He ran the most opaque White House in modern history, not least due to his reliance on family members (automatically loyal) and several high-profile defenestrations of whistleblowers. I have a feeling stuff will be coming to light for quite some time. The spying on the media story that broke a few weeks ago, for instance.
Perhaps Ivanka stayed removed from Trump’s worst abuses, perhaps not.
