Republicans are targeting Americans making $40,000 or less a year as the main beneficiaries of the fourth stimulus package still held-up at the Senate, but which they now intend to pass before August 15. This will leave out more than 25 million middle-class Americans who benefitted from the first stimulus payments.

An indication of the GOP's priorities in their version of the Democrats' HEROES Act is majority leader Mitch McConnell, R-Ky., pushing this amount.

"I think the people who have been hit the hardest are people who make about $40,000 a year or less," said McConnell. "Many of them work in the hospitality industry. The hospitality industry, as all of you know, just got rim-racked -- hotels, restaurants -- and so (more stimulus checks) could be part of it."
