The shutdown, triggered by President Donald Trump’s insistence on funding for a wall along the U.S.-Mexico border, was in its 20th day Thursday. Hundreds of thousands of federal workers were expected to miss paychecks Friday, with a little more than half of them still working but without pay. Other key federal services are suspended, including some food inspections, as budgets for numerous federal agencies haven’t been passed and signed into law yet. Federal employee unions have held rallies in other states and Washington, D.C., this week, in some cases working with Democratic leaders to try to highlight what they say are the effects of the shutdown.
