Congress has spent months dithering over Zika funding. President Barack Obama asked for $1.9 billion in emergency cash to fight the virus in February. Republicans who control both houses of Congress want to offer less, and Democrats have rejected bills that they say have unacceptable political extras written in.
Senate Majority Leader Mitch McConnell now says Zika funding is likely to be included as part of a last-minute spending measure called a continuing resolution. The federal budget year runs out at the end of September.

There's no agreement on a final budget, but a CR, as the measure is called, would provide three months of funding so the federal government does not have to close — something that last happened in 2013.
Federal health officials say three months worth of money is far from ideal.
