Donald Trump calls Brussels a "horrible city" after it's attacked

Following Tuesday's deadly attacks in Brussels, Donald Trump, the Republican presidential front-runner, knocked off a quick succession of TV interviews in which his talking points evolved, enlarged, doubled back on themselves, and generally seemed of a piece with the candidate's improvised foreign-policy platform of being terrified of Muslims. The note he returned to again and again was that Belgium's capital was a “horrible city” brought low by Muslim immigration. He also endorsed the use of torture (again), flip-flopped on whether he would shut down the border were he president today, and warned that a similar violence was coming to the U.S.
