Jamie Rowen, associate professor of legal studies and political science, is interviewed about President Donald Trump’s executive orders regarding immigration. “We have three branches of government, and the legislative branch, Congress, is supposed to do a lot of the lawmaking in this country. And so, when an executive order does something that Congress is supposed to do, it’s generally considered not valid,” Rowen said, referencing Trump’s other efforts to use his executive power to shut down government agencies or departments.
