With his voice cracking, Gov. Steve Beshear paid respects Wednesday at a memorial service in a packed Capitol Rotunda to one of his best friends and trusted confidants, chief of staff Mike Haydon. Haydon died unexpectedly Sunday at his home in Springfield of a heart attack. He was 62. Current and former state and federal officials, legislators and co-workers crowded into the Capitol to remember the man who became Beshear's chief of staff in 2010 after having served as his legislative liaison.
