Several lawmakers have declared they will decline their paycheck or will donate it to charity in solidarity with civilian workers furloughed or working without pay.

Federal workers received their regular paychecks last week for work completed before the shutdown, but if a spending agreement is not reached soon, thousands could see a delay in paychecks scheduled for next Friday.

About 800,000 federal employees at several agencies — Agriculture, Commerce, Homeland Security, Housing and Urban Development, Interior, Justice, State, Transportation, and Treasury — face tough financial decisions.

“It’s very difficult to figure out how long we can survive with the savings we have,” David Arvelo, a health communications specialist at the Food and Drug Administration, told CNBC.

Utah Rep. John Curtis introduced the “No Work, No Pay Act of 2019” on Thursday to freeze congressional pay when any federal agency undergoes a shutdown due to a lack of funds normally allocated by Congress.
