M<\/span>r Trump said: \u201cTerrible! Just found out that Obama had my \u2018wires tapped\u2019 in Trump Tower just before the victory. Nothing found. This is McCarthyism!<\/p>\n \u201cIs it legal for a sitting President to be \u2018wire tapping\u2019 a race for president prior to an election? Turned down by court earlier. A NEW LOW!\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n Mr Trump added: \u201cHow low has President Obama gone to tapp (SIC) my phones during the very sacred election process. This is Nixon\/Watergate. I\u2019d bet a good lawyer could make a great case out of the fact that President Obama was tapping my phones in October just prior to Election.\u201d<\/p>\n President Richard Nixon resigned in 1974 after a long scandal that began with the discovery of a break-in at the offices of the Democratic National Committee in Washington and involved the bugging of political opponents.<\/p>\n A spokesman for Mr Obama denied the allegations as \u201csimply false\u201d.<\/p>\n On Friday Fox News asked Paul Ryan, the House Speaker, about the suggestion that a FISA warrant had been issued by a court.<\/p>\n He said: \u201cNone of us in Congress have been presented with evidence to the contrary.\u201d<\/p>\n Under US law, in order to approve a warrant authorising electronic surveillance of Trump Tower, a FISA court would have to have found probable cause that the target of the surveillance was an \u201cagent of a foreign power\u201d.<\/p>\n<\/div>\n
