With the US government partial shutdown now in its third week, it's not just federal workers who are feeling the pinch.
The closure of some offices, museums and national parks means fewer customers for small businesses. And after President Trump said the shutdown could last for "months of even years", there are growing concerns about the economic impact of the shutdown.
From Washington, Harry Horton reports.

Outside Washington's National Portrait Gallery a line of food trucks gathers every lunchtime. But the rush of customers has all but disappeared.

"Sometimes you have the line...spy museum there, this museum here, but you have nothing, literally no tourists."
Mohammed Badah's falafel food truck relies on the city's thriving tourist scene. But with the partial government shutdown keeping museums closed - visitors have stayed away and his business has dried up.

"This area, I can do like 80 customers easily. But last week the bst day I did was 20 customers, so that was really hard for us…
"It's not easy for people like us, small businesses like us. All thesee guys we are day to day to day to day. Not even paycheck to paycheck. We are a daily process. And hopefully they will find a solution for that."
Washington has become more familiar with government shutdowns in recent years, but this one is now the second longest in US history. If it lasts another week, it will be the longest ever.
The National Zoo is closed - even its famous panda cam switched off. Only essential staff remain to care for the animals. Outside Washington, national parks that have remained open are considering charging entrance fees. And at airports, the Airline Pilots Association has warned the shutdown is affecting the "safety and security" of America's airspace as security agents work without pay.
In the meantime, some government staff may decide to seek other work. Maureen Conway is an economist with the Aspen Institute.
"If it goes on very long, instead of saying 'when is this going to end? When do I go back to work?', they're all starting to look for other jobs. How do you maintain an effective set of government services of you can't maintain an effective government workforce? You can't maintain an effective government workforce if you can't pay them."
The Trump Administration has admitted the shutdown could affect America's GDP.
But as Democrats and President Trump dig in their heels, government workers and businesses can do little but watch on and hope.
