The White House charged Wednesday that Republicans are ignoring the threats posed by the Zika virus by refusing to provide more funding to fight it, and said the U.S. needs to quickly authorize $1.9 billion in new funds after the first documented U.S. case of a baby born with a Zika-related brain condition.

Presidential press secretary Josh Earnest said it’s “unclear at this point” whether the extra funding would have made a difference in the baby’s health, but said Republicans should still take heed.
