The Capital Area Food Bank in Washington D.C.
Chuck Bean, head of the Nonprofit Roundtable of Greater Washington, says many organizations that receive federal grants can't handle a prolonged shutdown.
"This could mean even further delays in reimbursements," he says. "And you know that most direct, on-the-ground service groups do not have the kind of cash flow to cover delays in payments."
Beyond that, however, Bean is more worried about how the shutdown will affect federal employees low on the GS pay scale, many of whom are living paycheck to paycheck.
"These folks will need help," he says. "I think the food banks need to gear up. I think non-profits providing emergency assistance will need to be ready. And I think there will be a great deal of anxiety and our mental health organizations ought to be ready."
If no deal is reached in Congress, a government shutdown would begin at midnight tonight.
