Nearly 18 months after Congress came to the rescue of jobless Americans, its historic expansion of the nation’s unemployment benefits system expired nationwide this weekend. Lawmakers, who extended the three pandemic programs in December and March, are not expected to renew them again.

A key component of the relief effort was a federal weekly supplement for out-of-work Americans. Initially, the jobless received a $600-a-week boost from April through July of 2020. Congress then revived the enhancement in late December but reduced it to $300 a week.
