Democrats on Friday called on the Republican-led Congress to abandon the summer break and return to Washington to pass a bill to fight the Zika virus, now that Florida has said it believes people are at risk of contracting the virus from mosquitoes inside the United States.

“House and Senate must return to Washington immediately to provide the Zika funding public health officials need to protect Americans,” Senate Minority Leader Harry Reid tweeted. The Nevada Democrat also said Americans “can’t wait” until lawmakers return in September.
