Donald Trump: 21 things the Republican believes

Donald Trump is the frontrunner in the Republican race to be the presidential nominee for next year's election. What are his policies and beliefs?

1. Arab-Americans cheered the attacks on 9/11.Trump repeatedly claimed that on 11 September, 2001, there were thousands of Arab-Americans celebrating in New Jersey after two planes flew into the Twin Towers. He says such public demonstrations "tell you something" about Muslims living in the US, however there are no media reports to back up the claim.

2. There should be surveillance on US mosques. Trump believes Muslims should be tracked by law enforcement as a counterterrorism initiative. He has walked back some comments about keeping a database on all American Muslims, but says he doesn't care if watching mosques is seen as "politically incorrect".
