Final answer:
The specific branch of Congress that struggled with the Fair Housing Act isn't detailed, but historically, both the House of Representatives and the Senate faced difficulties due to Southern Democrat and conservative opposition to civil rights legislation. The Fair Housing Act passed in 1968 amidst these struggles.
Step-by-step explanation:
The branch of Congress that had a hard time passing the Fair Housing Act was not explicitly specified in the information provided. However, considering the historical context, both the House of Representatives and the Senate faced challenges in passing civil rights legislation during the 1960s due to the presence of conservative Southern representatives and Republican opposition. In general, civil rights bills often encountered significant resistance in Congress.
In 1968, the Fair Housing Act, which aimed to eliminate housing discrimination, was finally passed. This landmark legislation was an extension of the civil rights agenda that included the Civil Rights Act of 1964 and the Voting Rights Act of 1965, both of which encountered similar struggles in Congress due to opposition from Southern Democrats and conservative lawmakers. Over the years, the Fair Housing Act has been strengthened, but enforcement and adherence to its principles continue to be a challenge.
