Final answer:
Theodore Roosevelt maintained segregation and discrimination despite the crucial support from Black military units in Cuba, as he did not pursue civil rights reforms in order to maintain political support from certain constituencies.
Step-by-step explanation:
Despite the crucial support provided by Black military units during the campaign in Cuba, where they fought alongside Theodore Roosevelt and his Rough Riders, Roosevelt's response to racial matters at home reflected the complicated political landscape of the time. His administration maintained the status quo of segregation and discrimination, evidenced by the dishonorable discharge of three companies of black infantry after a violent incident, and his reluctance to pursue civil rights legislation that might alienate his Southern Democratic constituency. While Roosevelt did meet with Black leaders at times, he also refrained from advocating for meaningful civil rights reform.
