Jasmine Tool is now scrambling to find a way to pay for nutrients that keep her alive. She said Thursday that she only has enough of the formula that she gets through a feeding tube to last through Friday.
Tool's situation is unusual. The U.S. government has said employees with active insurance will not experience lapses during the shutdown.
Democratic U.S. Sen. Ron Wyden of Oregon pointed to Tool's plight to call for an end to the four-week-long shutdown.
Tool has a brain tumor and a paralyzed stomach from a condition called gastroparesis.
