Trump is under unprecedented pressure inside America from forces that hate America. I mean Democrats and some Republicans and who is behind them.
Deviating attention from the real thing is the best tactics to deceive people and to smear somebody. Trump has done great things for the USA already, in his few months more than some presidents did in their one or even two terms in office, like Obama for example.
Difficulties with the right staff is a sign of a deep, deep crisis in the American politics and the so-called "chaos" just shows seriousness of Trump to do what's right for the US. It's not easy to head a revolution in a country so deep in self-destructiveness.
The real question is, what does Trump stand for, what he has done and doing for America and how it affects common people. Not what is happening at this moment with the staff of his administration.
You can have "peace and harmony" in the White House and lead the Titanic of USA straight towards an iceberg (Obama etc). "Chaos" is in fact a real fight. Although he's a strong man and his love for the USA is huge, he can never defeat the forces behind Democrats etc because they're too strong. But at least he's trying.
It's a tactics of lies. To distract from the real issues and on purely superficial basis to accuse of something that Trump is not.
