Why did Thomas Jefferson criticize only the British monarch, not the British Parliament?

King George abused his power in Parliament, something Parliament had no control over.

Explanation:

Thomas Jefferson criticized the British monarchy and not Parliament, for one reason. King George was not able to delegate sovereign power over the colonies on his own, instead he would have to work through Parliament instead. Given this, it wasn't really parliament who was responsible for the taxation or rule over America but rather the King who abused his power in Parliament.
