In a significant break from the policy of the Obama Administration, President Trump is open to conducting joint strikes between U.S. and Russian forces on the Islamic State group, White House Press Secretary Sean Spicer said Monday. After the Pentagon disputed Russian reports that such coordination had already taken place, calling it “rubbish,” Spicer maintained in his first press briefing that the new president would be open to such an effort. “The president has been very clear that he’s going to work with any country that shares our interest in defeating ISIS,” Spicer said.
