Apparently John Kelly told the White House staff to check their opinions at the door. The only opinions that matter are those of Trump.
On taxes, he said he pays them, but doesn't like to.
I can see why, his military retirement is about $275,000 per year, which is more than he made on active duty. His and dependents health care is almost 100% covered.
Then add in his salary for being Chief of Staff, about $175,000.
What's notable is they he does not like paying taxes, but 100% of his salary and health care comes from the taxpayers.
