Curtis Morrison

A liberal Super PAC being investigated for bugging Senator Mitch McConnell’s Louisville office is shutting down. The website Politico reports documents filed late last week with the Federal Election Commission show the agency approved a request by Progress Kentucky to close its operations.

The Super PAC was aiming to knock off Kentucky’s senior Senator, who is one of the top targets in the cross-hairs of Democrats in the 2014 election cycle.

Ultimately, the group raised just over $14,000, with only $1,000 in the bank at the end of June.

Curtis Morrison, who was serving as spokesman for Progress Kentucky, is accused of secretly recording a strategy session attended by Senator McConnell and re-election staffers. The FBI is reportedly investigating how the recording was made. The Kentucky Democratic Party has distanced itself from Progress Kentucky and Morrison, who has taken to the internet to solicit money for his defense fund.

The recorded McConnell strategy session contains audio of staffers discussing tactics they would use against actress Ashley Judd, had she challenged McConnell in the 2014 Senate race. At least one staffer talks about using Judd's history of depression against her.

U.S. Justice Department prosecutors are joining the criminal investigation into secret audio recordings made inside Kentucky Senator Mitch McConnell’s Louisville campaign headquarters.

In February, a liberal activist named Curtis Morrison secretly recorded McConnell and re-election campaign staffers talking about tactics they would use against actress Ashley Judd, should she challenge McConnell in next year’s election. Judd later said she wouldn’t run for Senate, but Morrison gave the recordings to Mother Jones, a liberal political magazine that published the audio and transcripts at its website.

McConnell has demanded anyone involved in the secret recordings be prosecuted.

Politico reports that any attempts to subpoena evidence from Morrison would probably need the approval of U.S. Attorney General Eric Holder, who has to sign off on any such subpoenas for journalists. Morrison has worked as a paid freelancer for a Louisville-based online news outlet, in addition to his work with political groups that have said their goal is to defeat McConnell in 2014.
