Jeb Goes After Trump in GOP Debate

Republican presidential candidate Donald Trump tussled with rivals at the fifth GOP debate on Tuesday night, with Jeb Bush questioning whether the real-estate mogul was tough enough to handle the threat of terrorist attacks. The debate was mainly focused on national-security concerns and ISIS, as it was colored by the Paris attacks and the San Bernardino, California, shootings. The former Florida governor attacked Trump and Sen. Ted Cruz on their strategy against ISIS, while Cruz clashed with Florida Sen. Marco Rubio on government surveillance and immigration. “You’re not going to be able to insult your way to the presidency,” Bush said to Trump after a heated exchange. “Leadership is not about attacking people and disparaging people. Leadership is about creating a serious strategy, to deal with the threat of our time.”
