There are reports that samples from Saturday's deadly attack in Syria have tested positive for chemical weapons. NBC News reports that U.S. officials say blood and urine samples from the attack suggest the presence of chlorine gas and an unidentified nerve agent. The officials told NBC they were "confident" in the intelligence but not 100-percent sure. The officials also say the U.S. and other countries have compiled images that suggest the Syrian government carried out the attack. The Syrian government has denied involvement. President Trump is weighing options to retaliate.
