He knows how it works and won't be shedding any tears.
Trump admitted he likes the guy and that he's a good administrator but they just disagreed on too many policies that Trump wanted to push and Tillerson counseled against.
Even with Tillerson's denial of knowing why he was canned, he knew this was coming. Besides, Trump doesn't need a reason.
Trump's a well-seasoned businessman so he fired him. In Trump and Tillerson's world, no big deal.
In Nancy Pelosi's Botox addle-brained, liberal, political world, big deal.
This is merely further proof that pe-LOUSE-i is a lunatic. Hahaha.
