John Dowd, a former Marine Corps captain and veteran Akin Gump Strauss Hauer & Feld litigator who retired from the firm earlier this year, appeared last week on SiriusXM’s Mad Dog Sports Radio with Christopher Russo to discuss his investigation 26 years ago that led to a lifetime ban of Major League Baseball icon Pete Rose. It did not go well.

Russo, no stranger to on-air shouting matches, diatribes and other assorted audio tirades, almost immediately got into a verbal sparring match with the irascible former head of Akin Gump’s criminal litigation group in Washington, D.C., which led the latter to abruptly hang up the phone a little more than four minutes into an interview with the loudmouthed talk radio host.
