Former Attorney General Kathleen Kane refused to testify, invoking the Fifth Amendment, at a court hearing in which an accused killer was challenging wiretap evidence, according to a report on Philly.com.

Price Montgomery, an accused drug dealer charged with shooting and killing a witness, is challenging a 2014 wiretap that was authorized by former Deputy Attorney General Adrian King when Kane was on vacation in Haiti.

Kane, feuding at that time with King, left for the trip without leaving a designation letter that would allow him to make decisions in her absence. King, according to Philly.com, approved the wiretap using an auto pen to add Kane's signature to the document.

Now Montgomery is challenging the validity of that authorization, and wants the evidence gathered as a result of that wiretap thrown out.

King, who later testified against Kane at her trial, said during the hearing Tuesday Kane verbally approved the wiretap in a phone call.

However, Philly.com reported that when Kane took the took the stand at the hearing, she refused to answer questions, citing the Fifth Amendment.

Kane was sentenced to 10 to 23 months in prison after she convicted last year on perjury and obstruction charges. She is currently free while her appeal makes its way through the courts.
