It might be a good time for President Trump to say something like, "On behalf of the Republican Party, I'd like to say 'you're welcome.' The Republican Party, of which I have the very great honor of being de facto head, ended slavery in this country almost 250 years after enslaved Africans first came to these shores. In addition, Republicans granted citizenship to the freedmen, and recognized their right to vote. It took the next hundred years to secure those rights against the white supremacist views of Democratic Klansmen, and other benighted souls. So to everyone who ever benefited from that, which I believe is all Americans, 'you're welcome.'"
