The administration and Republicans have aligned behind a nearly 250-page stimulus package that would cost approximately $1 trillion, though a hard top-line figure has not yet been released.

But experts have suggested the amount is too small to combat the fallout from the coronavirus, which has sent shockwaves through major industries and caused several businesses to curb their hours or close altogether as people are being told to practice "social distancing” to try to curb the spread of the disease.

Tony Fratto, a former staffer in the George W. Bush's administration, told NBC News that the package "probably needs to be $2 trillion."
