They did so for a good reason:

Senate Democrats on Sunday blocked action on an emerging deal to prop up an economy devastated by the coronavirus pandemic, paralyzing the progress of a nearly $2 trillion government rescue package they said failed to adequately protect workers or impose strict enough restrictions on bailed-out businesses.

The party-line vote was a stunning setback after three days of fast-paced negotiations between senators and administration officials to reach a bipartisan compromise on legislation that is expected to be the largest economic stimulus package in American history — now expected to cost $1.8 trillion or more. In a 47-to-47 vote, the Senate fell short of the 60 votes that would have been needed to advance the measure, even as talks continued behind the scenes between Democrats and the White House to salvage a compromise.

There is an even better reason not mentioned, that the plan included a $½ trillion slush fund that Trump could use for his own personal of political benefit:

While the indicators are lagging, the U.S. economy is in a recession that will very likely be extremely deep. It’s likely that real GDP falls at double-digit pace in the quarter that begins next month and the unemployment rate more than doubles. If that sounds implausible, history shows that in sharp downturns, the unemployment rate takes the elevator up and the stairs down.

………

But even as Congress must speed toward completion and passage of this legislation, there is time to avoid wasting resources, and there is one, large part of the bill—$500 billion, according to the Washington Post—that threatens to create a “slush fund” for businesses with virtually no oversight, no benefits for workers, and far too much discretion for President Trump to dole out goodies to himself and his cronies.

The lending mechanism in question allocates $500 billion to backstop (i.e., repayment is guaranteed by the government) private-sector loans to the tune of $50 billion to airlines, $8 billion for cargo carriers, $17 billion for businesses “critical to national security,” and $425 billion for businesses, states, and cities.

To be clear, there’s nothing wrong and a lot right with providing resources of these magnitudes for businesses. The bill also proposes $350 billion for small business with a smart, built-in incentive to help workers: if employers use a portion of the loan to maintain their payrolls, that portion is forgiven.

But the $500 billion carries no such incentives (there is a requirement that CEO can’t raise their pay over last year’s level, but that could mean just “restricting” a CEO to a $15 million paycheck, an extremely mild condition). Nor does there appear to be adequate oversight or “underwriting,” the process by which banks determine credit worthiness, leading Sen. Warren to tweet that it “sounds like Trump hotel properties like Mar-a-Largo could receive huge bags of cash – and then fire their workers – if Steve Mnuchin decides to do a solid for his boss with taxpayer dollars.”

………

Yes, time is of the essence, but Democrats must use their leverage to remove this Trump/Mnuchin slush fund while they quickly negotiate the attaching of pro-worker conditionality to it. The main thing for this moment is to get the help to families (direct cash) and small businesses out the door.

There is no obvious reason that we can’t do something similar for larger firms by making loans available for purposes of meeting their payrolls. If the airlines and other especially hard hit businesses need additional assistance to get through the crisis, we can work through a well-designed package that ensures both that shareholders and top executives share the pain and that President Trump can’t use the money to help himself and his friends.

If the funds can be used in a corrupt manner, the Trump administration WILL use those funds a corrupt manner.

They will choose to benefit the Trumps, and the Kushners, and politically connected Republicans unless accountability is built into the plan.
