where in the transcript did he say to go on CNN? I didn't see that....What does rooting out corruption have to do pressuring a President of Ukraine to go on CNN to announce investigation of Bidens?
The answer is NOTHING. It has to do with corrupt conduct of foreign policy for political gain, a clear abuse of office.
If Trump wanted to PROPERLY address what he saw as corruption then he would file a complaint with DOJ and let them drive confidential investigation, involving his office only if Ukraine's authorities refused legitimate request for cooperation.
