[Q]: (CNN) The Trump White House is at once decidedly leaky and totally unknowable. We know there's lots of jockeying and infighting among President Trump's top advisers, but what we don't really know is what specific roles each of them play or who, at any given time, has the President's ear. Enter Eric Trump. The second youngest of the male Trump offspring, Eric gave an interview to The Telegraph newspaper in which he offers a telling glimpse into the role his sister, Ivanka, plays vis-a-vis the other advisers in his father's orbit. Here's what he told the paper: "Ivanka is by his side in Washington. She is not involved in everything. I think she comes and goes with issues she deeply cares about but when you get to a certain level of power a lot of times, and you see this in business too, a lot of times people will say yes just because you happen to be the boss....Ivanka Trump can say "no" to her dadGrowing role for Ivanka suggests her family is not pleased with how the White House is running 
 Question:But, seen against the backdrop of _'s first 80-plus days in the White House, Eric Trump's comments about his sister's role are far more intriguing.
[A]: Trump White House
