Washington( CNN) President Donald Trump called on Qatar to stop funding terrorism, claiming credit for and endorsing the decision of Gulf nations to ostracize their neighbor, even as US Cabinet officials said their siege is hurting the campaign against ISIS.

“We had a decision to attain, ” Trump said, describing conversations with Saudi Arabia and other Gulf countries. “Do we take the easy street or do we finally take a hard but necessary action? We have to stop the funding of terrorism.”

In doing so, the President’s tone, if not his message, clashed with his most senior national security officials, highlighting the often mixed messages emerging from his administration since the Qatar crisis began Tuesday.
