She's hardly a shill. She's one of his staunchest supporters. She, like many others, is getting impatient that the wall isn't going up. She's a hardcore conservative who has been writing for years about how we are losing the country because of uncontrolled immigration. She's very passionate about it. She believes that even if POTUS does nothing else besides build the wall then his presidency permanently becomes a 5-star legacy. She also believes that the opportunity for the wall to get done is slipping away. She's not entirely wrong about that. POTUS has to put his foot down and demand the money for the wall. He passed up two really good opportunities to do this already.
Reality check: he's not going to get any money from the Democrats for the wall after the new Congress is sworn in (Maxine in charge of the money). We all know that.
