(AP Photo/Jacquelyn Martin) (Jacquelyn Martin/AP)The federal government is nearing a partial shutdown, with a range of effects on public services and the broader U.S. economy. Other functions — like NASA’s space missions, President Donald Trump’s immigration crackdown and certain public health work at FDA and the USDA — would continue. About 86% of the agency’s staff would remain on the job because their work is deemed essential or they are funded by non-federal sources, according to the administration’s shutdown plan. Employees deemed to “excepted” from shutdown plan are those whose jobs are necessary to respond to emergencies and national security. More than 1,700 employees would be required to go to work if a shutdown begins on Wednesday, the memo said.
