A review by The Associated Press found that at least half of the states are not going to meet White House’s deadline and some aren’t even bothering to try.

Only a handful of states, including West Virginia and Rhode Island, have said they’ve already tested every nursing home resident.

Many states said the logistics, costs and manpower needs are too great to test all residents and staff in a two-week window. Some say they need another week or so, while others say they need much more time. California, the most populous state, said it is still working to release a plan that would ensure testing capacity for all residents and staff at skilled nursing facilities statewide.

And still other states are questioning whether testing every nursing home resident and staff, regardless of any other factors, is a good use of time and money.
