The problem for Republicans has been throughout Comey’s testimony that they have not been able to harm his account of his conversations with Trump. There have been so many bad moments for Trump during this hearing. Comey explained that he took notes on his conversations with Trump because he believed that Trump would lie about the conversations. Comey said that Trump is being investigated for obstruction of justice, and he said that he took Trump’s words about letting go of the investigation of Mike Flynn as an order. James Comey is using his credibility and delivering testimony that is another building block in the case against Trump.
