Dems zing House GOP over Zika funding

Senate Democrats knocked Republicans Wednesday over lack of progress in funding a fight against the Zika virus.

It has been months since President Obama requested $1.9 billion to fight Zika, and lawmakers are still hashing out how — and how much — to tackle the issue. 
"We need to act yesterday," Murray said.
The Senate passed $1.1 billion in funding as part of a wide-ranging appropriations bill last month, while the House passed a stand-alone bill for $622 million in Zika funding. 
The Senate has not yet voted to enter a conference committee with the House to resolve the differences in their funding packages. 
"Republicans and Democrats worked together to pass a bill here in the Senate to provide funding and resources. The House passed its own version. We're ready to go to conference and complete a final bill. I'll have more to say on that soon," he said. 
He added on Twitter that "we will be working with the House to finalize a version."
Democrats, however, are warning that they aren't willing to accept anything less than the $1.1 billion passed by the Senate. Sen.

They're also expected to continue to push for the full $1.9 billion. Sen.

He added Wednesday that the fight over funding is largely a "political problem." 
"The House sticks their head in the sand," he said. 
How the two chambers will work out their differences is largely unclear. House Republicans have balked at accepting the Senate's deal, which is unpaid for.
