Can you provide some examples that you believe make him a RIINO?
Yes. He said Biden was elected legitimately, was his Presudent and he looked forward to working with him. Read this.
For those who don't know or remember, in late January Cawthorn proclaimed Biden's legitimacy and stated the election was not fraudulent.
"Yes, I think I would say that the election was not fraudulent. You know, the Constitution allowed for us to be able to push back as much as we could and I did that to the amount of the constitutional limits that I had at my disposal. So now I would say that Joseph R. Biden is our president.""So when I contested to the election, that was within the constitutional guidelines that the framers had set up. But after I've done that and the electors and the delegates from each state elected Joe Biden as our president, I respect the office. He is my president, and I want to work with him to make sure that we can bring some meaningful change to the American people."
Since Biden's inauguration, Cawthorn has signed onto a letter along with 16 other GOP House freshmen, saying they look forward to working with Biden. Notably, Cawthorn is the youngest member of Congress in modern history, according to US House records, at just 25 years old.
