U.S. Rep. Joseph Kennedy III, a politician with a very well-known name but relatively little prominence outside of his home state of Massachusetts, will deliver next week's Democratic rebuttal to President Donald Trump's State of the Union address.
The speech will be the highest profile appearance of the 37-year-old Kennedy's political career, following his 2016 talk at the Democratic National Convention, where he introduced U.S. Sen. Elizabeth Warren. He has been a member of the House of Representatives since 2013.
"The national audience will get their first opportunity to really get to know him in a way that the people of Massachusetts have come to know him," said Peter Ubertaccio, a professor of political science at Stonehill College, outside Boston.
