WASHINGTON (Reuters) - U.S. Senators Marco Rubio and Bill Nelson of Florida asked Senate leaders to include additional funding for Hurricane Irma in a $7.85 billion disaster aid package for Hurricane Harvey passed by the House of Representatives earlier on Wednesday. Rubio, a Republican, and Nelson, a Democrat, said in a statement they made the request to cover costs expected to be incurred by the Federal Emergency Management Agency as Irma, a powerful Category 5 hurricane, approaches Florida.
