Doug Hughes, the Florida mailman who landed a gyrocopter on the lawn of the U.S. Capitol in April to call for campaign finance reform, has pleaded guilty to a single felony count of operating the tiny personal aircraft without a license. Hughes faces up to three years in prison and a fine of up to $250,000 at his sentencing in April. Hughes landed on the Capitol lawn carrying letters to every member of Congress urging them to pass campaign finance reform. Speaking Friday, Hughes said his flight exposed security gaps—and brought attention to money in politics.

Doug Hughes: “I don’t think there is any security breach now. I don’t think anybody can do what I did. So what I did, did the country a favor in terms of security, but I didn’t do it over security. I did it because I wanted to bring attention to getting the money out of politics and restoring democracy. That is the biggest threat we face.”

A new estimate by Wells Fargo projects a record $6 billion will be spent on political advertising in the 2016 election season—a 16 percent increase over 2012.
