Days after tweeting about 'Obamagate' and accusing his predecessor, Barack Obama, of committing crimes, US president Donald Trump was asked to specify what those exactly were. He replied: 'Obamagate, it's been going on for a long time, it's being going on from even before I got elected and it's a disgrace that it's gone on.' He continued: 'some terrible things happened and it should never be allowed to happen in our country again.' When he is again asked what the crime is, Trump says: 'You know what the crime is.'
