This is his SECOND hearing he did not attend. The first was from the Steering and Policy Committee of the U.S. House of Representatives invited Snyder to testify and then first hearing on Flint. Democrats questioned the failure of Rep. Jason Chaffetz, who chairs the House Oversight and Government Reform Committee, to ensure Snyder’s presence.

So this is two US Congress hearings on the Flint Water Crisis he has ditched. US House committees stated they could not Subpoena him.
