He noted the effect of the job cuts in Delaware will be "significant."
Delaware Governor Jack Markell called the news of layoffs deeply disappointing.
"For those affected by today’s announcement, they should know that the state will do all that it can in the coming months to assist them as they evaluate new opportunities," Markell said.
