NBC’s questioning of Ivanka Trump was more than appropriate. It should be just the start.

After all, Ivanka Trump bills herself as a champion of women and is a close adviser to her father and a frequent representative of the United States abroad.

Uncomfortable, yes. Inappropriate, no. (And yes, I thought a similar question to Chelsea Clinton about her father’s accusers during the 2016 presidential campaign was fair game, even though — unlike Ivanka Trump — she was not a government representative.)

The Ivanka Trump episode echoed White House press secretary Sarah Huckabee Sanders’s response to journalists about Kelly, the White House chief of staff, last October. Kelly got the facts wrong — or lied, if you will — when he tried to discredit Rep. Frederica S. Wilson, a Florida Democrat who had criticized the president for the insensitive way he spoke to a soldier’s widow in a condolence phone call.
