In an interview on Friday morning, President Barack Obama addressed reports of a potential devastating chemical weapon attack perpetrated by the Syrian government on its own people. In the sit-down, the president said the U.S. is still trying to confirm the reports but called it a "grave concern."

"There is no doubt that when you start seeing chemical weapons used on a large scale," he said, "and again, we're still gathering info about this particular event, but it is very troublesome."

He added that such a use would begin creeping closer to "some core national" interests that the U.S. holds, including ensuring no weapons of mass destruction are used, but also protecting our allies.

The president has said in the past that the use of chemical weapons would be a "red line" for America.
