Final answer:
The Fair Housing Act of 1968 was amended in 1988 to include protections against discrimination based on disability and familial status, providing HUD with increased enforcement capabilities.
Step-by-step explanation:
An additional amendment to the Federal Fair Housing Act of 1968 was added in 1988. This amendment expanded the coverage of the Fair Housing Act to prohibit discrimination in housing based on disability or familial status. Furthermore, the amendment also provided for new enforcement mechanisms, including providing the Department of Housing and Urban Development (HUD) with the power to enforce fair housing policies and to initiate investigations and conciliations. Grassroots movements and policy changes over the years, including during the Obama and Trump administrations, have sought to address and modify the enforcement and effectiveness of the Fair Housing Act.
