continued. the fallout was eerily predicted in an e-mail sent more than a year ago when the governor's special projects manager wrote, "this is a public relations crisis waiting to explode nationally." friday the governor admitted that he should have been more directly involved back when his aides first e-mailed about the problem. >> that's where i am kicking myself every day. i wish i would have asked more questions. i wish i wouldn't have accept-- would have send answers. i'm not going to have that happen again. >> reporter: snyder says he's working to expand health-care t coverage for flint residents and subsidize their water bills.
