Gov. Rick Snyder called Tuesday for addressing Michigan’s aging infrastructure over the next several decades, citing the Flint water crisis that has roiled his administration and a football field-sized sinkhole that formed recently in suburban Detroit. In his seventh annual State of the State address to lawmakers, the Republican also touted the state’s Medicaid expansion, which has provided health insurance to 600,000 low-income adults but which is in jeopardy as the GOP-led Congress seeks to repeal the federal health care law.
