The Pentagon has deployed several hundred Marines to northern Syria, the Washington Post and CNN reported this week. Their mission: firing long-range artillery to help recapture Raqqa, ISIS’s self-proclaimed capital city.

The Marines are equipped with M777 howitzers, which can fire GPS-guided explosives up to 25 miles.

That’s a big change from the “train, advise, and assist” role U.S. forces have been playing so far — although as with many previous troop deployments to Iraq and Syria, it was not debated, let alone authorized, by Congress.

But the White House press secretary brushed off a question about the move, saying that sending “several hundred advisers” did not amount to “hostile action.”

Right-wing radio host John Fredericks asked Sean Spicer on Thursday whether Trump was committed to seeking congressional authorization for new deployments.

“I think there’s a big difference between an authorization of war than [sic] sending a few hundred advisers,” Spicer replied. “And I think most in Congress would probably agree with that as well. I think that’s a big difference between a hostile action and going in to address some certain concerns, whether it’s certain countries in the Middle East or elsewhere.”
