"One of the reasons that I didn't come forward initially was, I didn't want me to be part of the story, so I released it without even saying that I made the recording, anonymously," Curtis Morrison told MSNBC.
"And then when I was identified, the spin that McConnell put out was so far from reality that I knew I couldn't fix it that day and I needed some time to reflect on it and to articulate it."
The recording revealed the details of a meeting between McConnell and his aides during which they outlined potential lines of attack against actress Ashley Judd, who was then considering running against the Republican in 2014, and Kentucky Secretary of State Alison Lundergan Grimes, who has not yet decided on the race.
In the recording, an aide to McConnell suggested Judd's past mental health problems and positions on religion could be liabilities for her on the campaign trail.
McConnell quickly accused Democratic activists of bugging his office, and a Kentucky Democratic official identified Morrison as the person responsible.
Morrison wrote that in the days following the audio leak, he lost a friendship, his apartment and his job.
He told MSBC that he wasn't concerned with the impact on his personal life, because he was passionate about revealing the content of the recording and defeating McConnell.
"The personal consequences to myself are really not that important. And really they haven't been that inconvenient, not more inconvenient than the suffering of Kentuckian families since McConnell has been in office," he said.
However, he acknowledged that the recording did embolden McConnell to campaign on the incident.
Morrison said it didn't occur to him that he might be breaking the law by recording McConnell as a non-participant in the conversation.
"I wouldn't say that it occurred to me that I was breaking the law. It did not feel as if I was breaking the law, it felt as if I was hearing a tyrant go on like he shouldn't be and the voting public deserves to know how he is," Morrison said.
The Kentucky activist said it was a misconception that McConnell was bugged. Morrison said he recorded McConnell through a wall, while in a the hallway of a public building.
