Um okay?  You had written this (below) re Trump and I genuinely am interested in any/all personal and libelous/slanderous "Fact Free" attacks Trump has made 'specifically  regarding' our President Obama.

 The only one I ever heard from pre-President Trump questioned  Obama's birthplace -but that is based on Obama's written/submitted Harvard Law biography stating that he was "born in Kenya, raised in Indonesia and Hawaii," so that isn't libel or slander.

>>>"...trump deserves to be sued a thousand times over for his repeated fact-free attacks on President Obama over the years ..." <<<
