On Tuesday, the Senate overcame a procedural hurdle and voted 68-29 to invoke cloture on an amendment to provide $1.1 billion of emergency funding to stop the spread of the Zika virus and develop a vaccine. The amount is less than the $1.9 billion President Obama asked for in February and which U.S. Senator Jack Reed has been advocating for, but more than the $622.1 million that House Republicans are proposing.
