What was the response if the US when Texas applied for statehood?

When Texas applied for statehood in 1845, the U.S. was initially hesitant due to concerns over the potential expansion of slavery and the possibility of conflict with Mexico, which still considered Texas its territory. However, public support for annexation was strong, and the U.S. Congress ultimately approved Texas's admission as the 28th state. This decision contributed to heightened tensions with Mexico, leading to the Mexican-American War. The annexation was officially completed on December 29, 1845.
