The White House’s evolving spending plan could be unprecedented in its size and velocity, dwarfing the stimulus bill passed during the Obama administration and the Troubled Asset Relief Program passed during the Bush administration. The current $1 trillion Trump plan would seek to spend $500 billion towards the cash payments to individual Americans, though some people wouldn’t qualify if their income is over a certain level.

The White House discussions with Republicans would aim to spend another $50 billion to help rescue the airline industry and $150 billion to prop up other sectors, which could include hotels, among others. Some Democrats have raised concerns about how these funds might be used and have called for putting restrictions on firms that receive emergency assistance to assure that employees aren’t laid off while executives pocket large bonuses.

One of the goals of the White House’s decision to seek $300 billion for small businesses in the plan would be to help firms continue paying employees, as there has already been a wave of layoffs, particularly at restaurants and other companies where business was suddenly halted as millions of Americans began staying at home under government warnings about contagion.
