Final answer:
Nixon tried to defund the Office of Economic Opportunity, but his efforts were thwarted when courts ruled it unconstitutional, preserving the agency.
Step-by-step explanation:
An example of President Richard Nixon's conservative policy towards Congress was his attempt to dismantle the Office of Economic Opportunity (OEO). Despite Congress's allocation of funds for the OEO, Nixon aimed to remove its funding and when that failed, he appointed a new director with the intention of obstructing the agency's function. However, this effort failed when the federal courts ruled that Nixon's actions to eradicate the OEO were unconstitutional, thus preserving the agency and its anti-poverty programs.
