Lawmakers are heading toward a battle over how much money to spend fighting the Zika virus.

The Senate agreed by a voice vote Wednesday evening to go a joint House-Senate conference committee on a wide-ranging appropriations bill that includes $1.1 billion in unpaid-for funding to combat the Zika virus.

"We're now ready to go to conference and complete a final bill."

Lawmakers will need to find a way to reconcile the Senate bill with the $622 million in funding passed by the House, where Republicans have balked at supporting the larger amount.

The House version also uses funding originally meant to combat the Ebola virus to pay for the Zika virus efforts.

But Senate Democrats also warned earlier Wednesday that they won't back anything less than $1.1 billion, with Sen.

Senate Democrats argue that Congress should pass $1.9 billion in Zika virus funding — the amount requested by President Obama.

But any measure would face an uphill — if not impossible — battle with Senate Republicans previously rejecting matching the president's proposal.
