UNITED NATIONS : Republican presidential front-runner Donald Trump has suggested that former President George W. Bush was partly to blame for the 9/11 attacks, igniting a new controversy.While speaking about national emergencies, Trump said that he would be a better president than his rival candidates or earlier presidents. “I think I’m much more competent than all of them. I mean, say what you want, the World Trade Center came down during his (George W. Bush) time,” Trump said on Bloomberg News Television.“He was president, OK. Blame him, or don’t blame him, but he (Bush) was president. The World Trade Center came down during his reign.” His rival Presidential candidate, Jeb Bush  rushed to social media to defend his elder brother and slam Tump. He  called Trump’s remarks “pathetic”, and said George W. Bush, as president,  kept America safe.Under fire from fellow Republicans and supporters for suggesting that George W. Bush shared in the blame for the 9/11 attacks,  Trump  repeatedly declined to engage with reporters about the matter Friday night. Trump regularly speaks with reporters at campaign events and often takes multiple questions in an impromptu manner, making his silence Friday all the more noticeable. When asked by a reporter after a rally at a local high school if he thought the attacks were George W. Bush’s fault, Trump, after pausing to listen to the question, walked away.
