Republican presidential frontrunner Donald Trump is never at a loss for words. As the world is still in shock and reeling from news of the terrorist bombings in Brussels Tuesday morning, the business mogul didn t hesitate to make truly despicable remarks about the attacks on Twitter, as well as insult President Barack Obama s historic trip to Havana, Cuba.In an interview with Fox Business host Maria Bartiromo, Trump used the terrorist attacks to imply that Obama s Cuba visit may correspond with setting up a little area in Cuba for the Muslim population.  Trump also said the bombings were a sure sign that if the United States doesn t secure its border, it is going to lead to just catastrophic problems.  The disgraced candidate actually had the nerve to say that a big part of the reason he has been  leading on the Republican side by a lot  was because of his racist, offensively strong position on building walls and controlling the border.Fox News was more than happy to follow Trump on his criticisms of Obama, with Bartiromo noting that it was  interesting  that the President would be speaking at a press conference during his last day in Cuba. She said: Isn t it interesting that now we understand that President Obama will give a live press conference later on today? He s probably going to discuss the terrorist attack from the brutal communist dictatorship of Cuba. So, what irony that is. Trump jumped in and asked, I wonder how many Muslims Cuba is taking in every year? I wonder if they re setting up a little area in Cuba for the Muslim population. Bartiromo moved right on through the interview, without even clarifying with Trump just why he would connect Muslim camps in Cuba to the President s visit. You can watch the video of Trump s disrespectful comments below:Now, the fact that Trump is making inflammatory remarks about Muslims is no surprise as he has been expressing anti-Islamic sentiments throughout his entire campaign. However, his remarks about Obama have different implications considering that Trump has become infamous for his claims that Obama was not born in America, and therefore should not be president. Trump started his own birther movement surrounding those claims, insisting that the President show his long-form birth certificate despite the overwhelming evidence that Obama was indeed an American citizen. Trump has also criticized Obama for making a speech at an American mosque, saying  Maybe he feels comfortable there. Just yesterday, Trump celebrated the fact that it was Obama s final year with a big  YAY!  while he spoke at the AIPAC conference. On the same day, Trump said Obama was the  worst thing to ever happen to Israel  during a town hall. It s becoming clear that Trump is now hell-bent on destroying Obama s image, despite the fact that the President has undoubtedly improved America and our relations with other countries.Featured image via Gage Skidmore
