Donald E. Williams Jr., a 21-year member of the state Senate and former president pro tempore, has been seriously injured in a car crash.

Few details were available Tuesday, but Williams, 61, is expected to fully recover from serious injuries that occurred during the weekend incident, said Jeff Leake, CEA president. Williams joined CEA in 2014 and was named executive director in 2017.

“Our entire staff is extremely optimistic about Don’s prognosis, and we look forward to his return after he has had time to rest and rehabilitate,” Leake said.

“From my many years of working with and next to Don I know my dear friend has the immense strength and courage necessary to overcome the challenges ahead. Don is one of the very best people I have been blessed to come to know in my 38 years in the General Assembly,” said Senate President Pro Tempore Martin M. Looney. Williams represented the 29th District towns of Brooklyn, Canterbury, Mansfield, Windham, Killingly and Thompson
