US President Barack Obama has warned White House contenders to avoid raising tensions, a day after a rally by Donald Trump was called off amid clashes. Speaking at a Democratic Party fund-raiser in Dallas yesterday, Mr Obama said, candidates should not resort to insults and certainly not violence against other Americans.
Mr Trump, who leads the race for the Republican nomination, cancelled his Chicago rally after fighting broke out between his supporters and protesters. His rivals and others have accused him of using inflammatory rhetoric.
Mr Obama will be standing down after November’s presidential election.
The clashes at Mr Trump’s Chicago rally on Friday began more than an hour before the event was due to start, and continued after it was cancelled.
