The senator, whose home state has an alarming number of Zika infections, is ridiculing fellow Republicans in Congress for refusing to back the White House’s request for $1.9 billion to fight the mosquito-borne virus.

President Barack Obama has an outspoken and unlikely ally in his push for more dollars to combat the rising threat of the Zika virus – former Republican presidential hopeful Marco Rubio.
