The House passed a $622.1-million bill targeting the Zika virus on Wednesday, but where it goes from there is uncertain.
The White House has already threatened to veto the House bill, calling it “woefully inadequate.”
On Tuesday, the Senate passed its own $1.1 billion Zika funding bill.
Besides the difference in funding level, the two bills differ in other important respects. The House version includes offsets making it budget-neutral, whereas the Senate would appropriate money as new, emergency funding.
