Troy Jackson said Sunday he will not apologize for telling Sen. Susan M. Collins to "shut up" last week during a heated debate in Maine's deadlocked race for the Senate.

Maine Democrat Troy Jackson says he doesn't regret telling Susan Collins that she should “shut up” after the Republican senator suggested that a protester who interrupted their recent debate was one of his campaign’s backers.

The Maine Senate campaign between Democrat Troy Jackson and Republican Sen. Susan Collins is heating up.
