Schatz said he’s not yet going to wade into details of how he’ll pay for his plan because he thinks there’s a double standard with Republicans and Democrats.

“I don’t play the pay-for game. I reject the pay-for game,” he said. “After the Republicans did the $1.5 trillion in unpaid-for tax cuts, and as we’re doing a bipartisan appropriations bill — which I support — which is also an increase in federal spending [that’s] unpaid for … I just reject the idea that only progressive ideas have to be paid for. We can work on that as we go through the process, but I think it’s a trap.”
