President Barack Obama Monday sent lawmakers an official $1.9 billion request to combat the spread of the Zika virus in Latin America and the U.S, AP reported. He is also requesting flexibility to use a limited portion of leftover funds provided in 2014 to fight Ebola to take on Zika, which has been linked to severe birth defects. Top House Republicans told the White House last week that the quickest way to get the money to fight Zika would be to use some of the approximate $2.7 billion that had been designated for the Ebola crisis but remains "unobligated." Consideration of a stand-alone Zika request could prove cumbersome, especially in a combative election year. Obama said Monday during a meeting with the nation's governors that he hoped to work with them in guarding against the outbreak of the disease. Obama said the $1.9 billion he is requesting would include investments in research into new vaccines and better diagnostic tools, and more support for Puerto Rico and territories where there are confirmed cases.
