Just to be fair to him, Trump did not lie about what happened in Sweden.  He meant there had been something on the news the night before about alleged trouble caused by wholesale immigration to Sweden.  He should have said "What I saw on TV last night about what is happening in Sweden."  And two days later there was a riot in an immigrant neighborhood in Sweden.  And according to what I have read, few of even the Middle Eastern immigrants in Sweden are Muslim.  Before anyone jumps to conclusions.
