What was the response of the congress to Polk's war message?

President James K. Polk's war message regarding the Mexican-American War received a mixed response in Congress. While many Democrats supported the war, viewing it as a means to expand U.S. territory, there was significant opposition, particularly from Whigs and some abolitionists who questioned the war's justification and motives. The debate highlighted deep divisions over issues of expansionism and slavery, ultimately leading to a narrow approval for the war. Overall, Polk's message ignited passionate discussions about American identity and the implications of territorial expansion.
