Trump still not backing Paris climate agreement: Italy's PM

President Donald Trump still refuses to back the 2015 Paris agreement to fight climate change, blocking efforts by world leaders meeting in Sicily to get the new U.S. leader to endorse the treaty, Italy's prime minister said on Friday."There is one open question, which is the U.S. position on the Paris climate accords... All others have confirmed their total agreement on the accord," Gentiloni said.
