The situation has become a bit confusing. The newspaper article states that Oklahoma is the 29th state to apply for a Convention of the States to address a balanced budget amendment. However, the COS website states that Oklahoma is now the 7th state to apply for a convention to address the comprehensive concept of limiting federal power using Georgia's language. (The first 6 states are AL, AK, FL, GA, IN and TN.)
One of these is true. I tend to trust the COS website because most newspaper journalists are hopeless when it comes to facts and the Constitution.
