How did members of Congress react to Jackson's removal plan?

The removal plan you are likely referring to is the Indian Removal policy associated with President Andrew Jackson during the 1830s. The policy aimed at relocating Native American tribes from their ancestral lands in the southeastern United States to lands west of the Mississippi River, in what is often referred to as the Indian Removal Act of 1830.

Reactions to Jackson's removal plan varied among members of Congress. Supporters, particularly Democrats, generally favored the policy for various reasons, including the desire for westward expansion, economic interests in the fertile lands of the Southeast, and a belief in the superiority of European-American culture.

However, opposition to the Indian Removal policy was also present. Many Whigs, along with some Democrats, opposed the forced removal on moral and ethical grounds. Prominent figures like Senator Theodore Frelinghuysen and Congressman Davy Crockett spoke out against the policy, arguing that it was unjust and inhumane.

The debate over Indian removal was a contentious and divisive issue in Congress, with the eventual passage of the Indian Removal Act in 1830 leading to the forced removal of thousands of Native Americans, most notably the Cherokee along the Trail of Tears in 1838.
