During the campaign, Trump said a Muslim ban would make America safer from terrorist threats, later walking that back slightly before his election to be a ban on people traveling from certain countries.
As president, he signed two executive orders temporarily banning refugees and citizens of several Muslim-majority nations from entering the United States, but both orders were quickly challenged on legal grounds. The first order's immediate implementation resulted in chaos at the nation's airports and borders before being stopped by the courts, while the second order was blocked by the courts before implementation.
Trump promised to "destroy" ISIS as a candidate, and his first public effort against the terror group was certainly a headline maker. The U.S.military dropped the so-called “Mother of All Bombs” in Afghanistan, where ISIS was believed to be establishing a new foothold in the border region near Pakistan. The impact on the terror group is still unknown.
