Secretary of State Rex Tillerson is speaking at Stanford University in California on Wednesday about the future of Syria, as the US looks to stabilize the region, CBS News reported.
Tillerson's speech, hosted by the university's Freeman Spogli Institute for International Studies and the Hoover Institution, is titled, "The Way Forward in Syria." In the past, Tillerson made it clear that the way forward in Syria does not include Syrian president Bashar Assad.
In his speech, Tillerson tackled the growing Iranian clout in Syria that "endangers the whole region".
In October, Tillerson said the "reign of the Assad family is coming to an end." Tillerson has also pushed peace talks.
But in recent days, troops backing Assad have said they want the US presence in Syria to end, according to Syria's state-run news agency.
The US has at least 2,000 troops in Syria, according to figures the Pentagon released in December.
