<human>:  Why did Eisenhower veto the Civil Rights Act of 1957?
<bot>: Eisenhower was a Republican, and he was against the Civil Rights Act of 1957 because it was a Democratic bill. The bill would have made it illegal to discriminate against people based on their race, color, religion, or national origin. The bill was passed by the Senate, but it was vetoed by Eisenhower.
