Equal Protection Clause

During Reconstruction, Congress enacted race-conscious programs primarily to assist newly freed slaves who had personally been denied many advantages earlier in their lives. Such legislation was enacted by many of the same people who framed the Equal Protection Clause, though that clause did not apply to such federal legislation, and instead only applied to state legislation. Likewise, the Equal Protection Clause does not apply to private universities and other private businesses, which are free to practice affirmative action unless prohibited by federal statute or state law.
