Bill Cosby is in the process of replacing his lead defense lawyer ahead of his scheduled retrial in November on sexual assault charges in Pennsylvania, according to media reports.

The media site Newsworks cites sources close to lead defense lawyer Brian McMonagle saying the respected Philadelphia litigator plans to file a motion as early as this week to withdraw as Cosby’s counsel.

The report suggests the move may have been prompted by conflicts beween McMonagle and Cosby rep Andrew Wyatt that arose during and after Cosby’s first criminal trial in the Pennsylvania case. A mistrial was declared in June when the jury was unable to reach a verdict in the case.

“Reached by phone Friday, McMonagle declined to comment for this story, but those close to him say among the issues that agitated him during the two-week trial was how Cosby’s public relations team — in particular, Cosby spokesman Andrew Wyatt — hijacked [the] spotlight after hearings to peddle theories and opinions not supported by McMonagle,” Newsworks reports. “Often, the comments were not underpinned by fact at all.”
