Timothy P. Murray agreed Thursday to pay $80,000 to settle charges that he collected $50,000 in illegal campaign contributions raised by two public officials, capping a controversy that derailed the former lieutenant governor’s political career.

Murray, who resigned in June to take a position as head of the Worcester Chamber of Commerce, collected tens of thousands of dollars in donations solicited by former Chelsea Housing Authority executive director Michael E. McLaughlin, according to Attorney General Martha Coakley.

McLaughlin, who has already been sentenced to three years in federal prison for lying to state and federal regulators about his $360,000 salary, was indicted Thursday by a state grand jury in several campaign violations including unlawful solicitation by a public employee.
