PHOENIX — Just before President Trump strolled onto the rally stage on Tuesday evening, four speakers took turns carefully denouncing hate, calling for unity and ever so subtly assuring the audience that the president is not racist.

Housing and Urban Development Secretary Ben Carson proclaimed that “our lives are too short to let our differences divide us.” Alveda King, the niece of Martin Luther King Jr., led everyone in singing a few lines of “How Great Thou Art.” Evangelist Franklin Graham prayed for the politically and racially divided nation and asked the Lord to shut the mouths of “those in this country who want to divide, who want to preach hate.” And Vice President Pence declared that “President Trump believes with all his heart … that love for America requires love for all its people.” Meanwhile, a supporter seated directly behind stage even wore a T-shirt that stated: “Trump & Republicans are not racist.”
