As the White House ordered strikes on Syria late Thursday, several of those old tweets were recirculating on Twitter, especially two in which he called for congressional approval before launching any military actions against the Middle Eastern country.
Following the regime of Syrian President Bashar Assad's use of chemical weapons on his own people, killing more than 80, Trump announced Thursday's attack in an official statement.
"Years of previous attempts at changing Assad's behavior have all failed and failed very dramatically. As a result, the refugee crisis continues to deepen and the region continues to destabilize, threatening the United States and its allies."
His stance on U.S. Syria policy under then President Obama dates back to 2013 when Trump began repeatedly criticizing the potential for American involvement.
