The Obama administration is asking Republican leaders to pass a Zika plan with bipartisan support, in a last-minute plea for funds to combat the virus before Congress leaves for an extended summer break.

According to a letter obtained by CQ Roll Call, two top administration officials petitioned GOP congressional leadership to pass “a funding plan that enjoys the bipartisan support needed to secure this critical funding during the short time remaining in the July session.” The letter was signed by Office of Management and Budget Director Shaun Donovan and Health and Human Services Director Sylvia Mathews Burwell.
