A bad thing is unfolding at NIH this week: It looks like the Trump administration is trying to replace key civil servant scientific leaders, the Institute Directors, with political hires. These directors control the NIH budget, tens of billions.

Tonight, I am voting no on a procedural vote on an appropriations deal that would re-open the government. Since July, I have been clear: to earn my vote, Republicans would have to do something to bring down the cost of health care for working and middle-class Michiganders. (1/4)
