The Bush family and Trump probably hate each other.
Jeb Bush was supposed to be next in line for the throne, and was the favoured candidate to win.
Trump beat him, referring to him as "Low Energy Jeb."
Then Trump accused George W Bush of lying to the people (probably true), and being incompetent (definitely true).
The Bush family vowed not to vote for Trump even though he was the Republican for President.
When Trump did become President, W and his wife attended the inauguration, celebrating the peaceful transition of power.
Later W was asked what he thought of the inauguration.
"That was some pretty weird shit," he replied.
For once, we are forced to agree with W.
