> It want to capital infusions for major banks and QE-related asset swaps
The $3 trillion figure is from the 2016 budget. I don't believe any capital was infused into banks à la TARP [1] last year. Also, QE refers to the Federal Reserve, instead of just buying Treasury bonds from banks, buying a broader portfolio of assets. This is done off the Fed's balance sheet and does not come out of tax proceeds.
