On this day, in 1987, President Reagan said: "If someone, even a friend, uses an ugly word referring to another's race or religion, let's make it clear we won't put up with it... There is no place for them in a democratic and free America." #MLKDay https://t.co/QqORyjIKlX

Illegal immigrant is not a race. Muslim jihadist is not a race. Stop calling people that want laws enforced RACISTS! #MLKDay

Hey @realDonaldTrump, when two of Dr. Martin Luther King's children call you out on #MLKDay , you're a racist.

Martin Luther King Jr. Day is a national day of service. President Obama on #MLKDay vs. Trump on #MLKDay https://t.co/cESJzKWojK
