Yes, it is the same organization.
I was never surprised at Liz Cheney; her father in my view is a malevolent incompetent whose advocacy for the Iraq war based on obvious lies was a complete disaster for many American families and for the people of Iraq. Kinzinger ran as a tea party conservative, comes from a devout family (many of whom have disowned him) and turned 180 on the people who supported him and for what? To appear on tv and be the puppet of those who hate everything he supposedly one time stood for?
