He has been featured on every major news network and interviewed by every major newspaper in Texas and worldwide. In addition, as a guest on Hannity, Fox Business, BBC News, Real America’s News, Newsmax, and many other news outlets, Daniel has been a strong and unapologetic voice for the right of self-government for Texans and the dangers posed by the overreaching and fundamentally broken federal government.
In 2005, Daniel founded the Texas Nationalist Movement, an organization dedicated to the political, cultural, and economic independence of Texas. In that time, as the organization’s President, the TNM has grown to become one of the largest political advocacy organizations in Texas and one of the largest independence advocacy organizations in the world. Representing the TNM, Daniel has testified on many pieces of legislation and is a regular fixture at the Capitol during the legislative session. As a result of the success of the TNM, Daniel has become a sought-after expert at conferences and meetings in Texas, the rest of the United States, and internationally on the issue of self-determination.
In 2011 he authored Line in the Sand, his first book, which addresses the roots of Texas Nationalism and the practical implications of national self-identity for Texans. In 2018, Miller released TEXIT: Why and How Texas Will Leave The Union, a four-time bestseller and is considered the ultimate guide to Texas becoming a self-governing, independent nation. TEXIT covers the motivations behind the modern movement for Texas independence and lays out a practical path to achieving it.
