The group, led by Texas Tea Party activist JoAnn Fleming, endorsed a different Tea Party candidate, Dwayne Stovall.
"Based on your response to media inquiries, you apparently believe you don’t have to answer to anybody," they wrote. "We disavow your lack of accessibility to the people of Texas during this campaign and these unethical activities. Whether these tactics are actually carried out by you, your associates, or a group of supporters – these are not the hallmarks of a statesman."
"We are looking for a bold, courageous leader with integrity – a leader who will make himself available to the people," they added. "Your actions have disqualified you."
