President Donald Trump denounced the chemical attack in Syria as an "affront to humanity" Wednesday, declaring that it crossed "many, many lines" and cannot be tolerated.

U.S. President Donald Trump blamed the Obama administration’s “weakness” for the deadly chemical attack in Syria’s Idlib province even though he once urged the former president to stay out of Syria.

White House spokesman Sean Spicer told press that the Obama administration is to blame for the Syrian attack that killed dozens.
