The federal budget was $3.8 trillion (with a "t") last year, and the deficit was $438 billion. Increasing the annual deficit by $100 million[1], or 0.02%, seems like a non-issue.
[1] $1 billion over 10 years is $100 million per year.
Agreed — it's a pretty weak reason to "strongly oppose" a bill, which is why I'm wondering how likely it would be for the Administration to change their position. Like, what percentage of the time do they issue a statement in strong opposition but then end up passing the bill anyway?
