Senate Majority Whip John Cornyn on Tuesday again pushed a series of mental health-related legislative fixes following last week’s deadly shooting at Umpqua Community College in Roseburg, Ore., pushing back on gun-control measures touted by President Barack Obama.”If the president would be willing to work with us, as we have worked together to reform our criminal justice laws in a bipartisan way as was announced last week, we could actually make some real progress by dealing with some of the root causes,” Cornyn said. “But as long as the president wants to demagogue this issue and use this as a way to drive Americans apart, rather than to bring us together in a common solution, we’re not going to be able to make the progress that we need to make in order to protect people from themselves and to protect the communities around them.”
