“Mike Castle was a great Delawarean who left a meaningful legacy," State House Republican Leader Tim Dukes said. "Throughout his decades of public service, from the Delaware House of Representatives to the U.S. House of Representatives, he embodied civility, pragmatism, and a willingness to work inclusively in pursuit of the common good.”

Castle was one of the most successful elected officials in Delaware history, serving two terms as governor and nine terms in the U.S. House.

“Today, Delaware mourns the passing of a remarkable public servant, Mike Castle. As governor and our state’s longest-serving U.S. representative, he embodied what it means to lead with principle, decency, and dedication.
