Senate Democrats on Tuesday blocked a critical funding measure needed to combat the spreading Zika virus, a move that will now make it impossible for Congress to send legislation to President Obama before July 4.

The $1.1 billion Zika language was included in a bill funding the Department of Veterans Affairs and military construction, which failed to get the 60 votes it needed to end debate and allow it to advance in the Senate. The vote failed 52-48, after Senate Majority Leader Mitch McConnell, R-Ky., changed his vote to “no” in the hopes of bringing up the bill again.
