A small aircraft known as a gyrocopter has landed on the west lawn of the US Capitol building.
The operator of the aircraft has been arrested by Capitol police.
The Tampa Bay Times tells the BBC the driver is Doug Hughes, a Florida post man who wanted to deliver a message about campaign finance reform to Congress.
The airspace around the Capitol and White House in Washington DC is restricted to official aircraft.
