Washington, D.C. residents who support the statehood movement sometimes use a shortened version of the Revolutionary War protest motto "No taxation without representation", omitting the initial "No", denoting their lack of Congressional representation; the phrase is now printed on newly issued Washington, D.C. license plates (although a driver may choose to have the Washington, D.C. website address instead). President Bill Clinton's presidential limousine had the "Taxation without representation" license plate late in his term, while President George W. Bush had the vehicle's plates changed shortly after beginning his term in office. President Barack Obama had the license plates changed back to the protest style at the beginning of his second term.
In what way has the phrase been protested?
