Last month, when the Republican Governor of South Carolina named GOP U.S. Representative Tim Scott to the U.S. Senate, the “first African American U.S. Senator from the South since Blanche Bruce of Mississippi in 1881” according to The State newspaper, thus becoming the only black -- Democrat or Republican -- in the Senate, ABC’s World News didn’t mention it.

Fast-forward to Wednesday night, and ABC anchor Diane Sawyer suddenly found it newsworthy that the Democratic Governor of Massachusetts appointed an African-American to replace new Secretary of State John Kerry, trumpeting: “Look closely at this picture. That is William ‘Mo’ Cowan of Massachusetts. He will be heading to Washington, DC soon and straight into the history books.”
