After Santa Anna signed the treaty with Texas and Mexico withdrew its troops, what became of Texas?

The treaty added an additional 525,000 square miles to United States territory, including the land that makes up all or parts of present-day Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. Mexico also gave up all claims to Texas and recognized the Rio Grande as America's southern boundary

Explanation:

The Treaties of Velasco are the modern term for what was called at their drafting a "Public Agreement" and a "Secret Treaty."

The Mexican Congress considered Santa Anna's actions scandalous and nullified both. Mexican conservatives removed Santa Anna as president and installed Anastasio Bustamante, and there was an agreement with the Mexican Congress that Santa Anna had "offered nothing in the name of the nation."
