Mo Cowan
29th United States Senator from Massachusetts (Class 2)

William Maurice "Mo" Cowan (born April 4, 1969) is an American politician who served as a United States senator from Massachusetts from February to July 2013. A member of the Democratic Party, he previously served as legal counsel and chief of staff to Governor Deval Patrick. Patrick appointed him on an interim basis to fill the vacancy left by fellow Democrat John Kerry, who resigned to become U.S. Secretary of State.

Cowan was the eighth African-American U.S. Senator and the second from Massachusetts after Edward Brooke. He was one of three African-American U.S. senators in the 113th Congress, along with Republican Senator Tim Scott from South Carolina and Democrat Cory Booker from New Jersey, although he did not serve alongside Booker, who took office on October 31, 2013.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
