There are two governing laws:
- The Fair Housing Act of 1968
- The Community Reinvestment Act of 1977
The make up in both of the Congresses of the time was majority Democrat in both houses! By ratios even higher than today;
- 90th Congress
- Senate -- 64(D) 36(R)
- House -- 247 (D) 187 (R)
- 95th Congress
- Senate -- 61(D) 39(R)
- House -- 292(D) 143(R)
So to try to blame this on the Republican party does not comport with the facts.
Further, to make it a violation of law to not give loans to persons in a certain area or certain type, without regard to any reason, is exactly the same as saying; "you must lend even if they look like a bad risk. Fail to do so at your own peril! Do not forget we control your existence as a business!"
