According to the sources, Trump had not made a decision about an intervention, however, is discussing a possible action with Defense Secretary James Mattis.

The sources said that Mattis will discuss several options with Trump at his Mar-a-Lago estate in Palm Beach, Florida, including cruise missile strikes from Navy ships.
