Which part of the passage best explains why the United States did not want to allow Indian Territory to become its own state?

The goal of the Sequoyah Convention was to draft a constitution for a proposed single state made from Indian Territory. Delegates were chosen in mass meetings held across Indian Territory. Until 1903, the Five Civilized Tribes and other tribes in Indian Territory had generally opposed all local and national efforts for statehood. In 1905, the end of tribal governments loomed, as prescribed by the Curtis Act, and the tribes knew they faced the prospect of joint statehood with Oklahoma Territory. Their desire for Indian Territory to be admitted as its own state resulted in the Sequoyah Convention, which met August 21 and 22 and September 5 through September 8, 1905. The convention drafted a constitution that was about 35,000 words in length, which was perhaps the convention's greatest contribution to Oklahoma history. But territorial leaders realized that the Republican-led US Congress was unlikely to admit a heavily Democratic Indian Territory. Still, single-state supporters and Indian Territory leaders pressed onward. However, the US Congress refused to consider statehood for the state of Sequoyah. Joint statehood, the joining of Indian Territory and Oklahoma Territory to form Oklahoma, occurred on November 16, 1907.
