In 2015, after Colorado Gov. John Hickenlooper announced his state would accept Syrian refugees, Sen. Cory Gardner, R-Colo., called on the Obama administration to “develop a comprehensive strategy to address the developments in Syria and eradicate the threat of [the Islamic State] once and for all.”

In 2017, after the United States launched 59 Tomahawk cruise missiles at a Syria air base, Gardner responded by reiterating the need for a “well-thought-out plan supported by the international community that will lead to a solution in Syria.”
