The Trump administration is considering new restrictions on free expression outside the White House that could see demonstrators forced to pay to hold protests. A proposal filed by Interior Secretary Ryan Zinke would see the National Parks Service close 80 percent of the sidewalks around the presidential mansion—including the entire sidewalk north of the White House—while requiring protest organizers to cover the cost of police and support services. Today, October 15, is the last day open to public comment on the proposal.
