The lawyer representing key impeachment inquiry witness Tony Bobulinski sent a letter on Wednesday to House Oversight Committee Ranking Member Jamie Raskin expressing frustration over the Democratic minority’s “abusive conduct” and “disingenuous mischaracterizations” of his client.

“We are watching the death throes of a political narrative that will be shattered upon the imminent public release of Mr. Bobulinski’s testimony before the House Committees on Oversight and Judiciary yesterday,” Stefan Passantino, Bobulinski’s lawyer, wrote. “The facts are before Congress and will soon be before the American people.”

“Minority assassination of Mr. Bobulinski’s character and grotesque mischaracterizations of his words will only serve to highlight the gaslighting and vilification Mr. Bobulinski has endured since he reluctantly came forward almost four years ago to share with the public the facts of his business experience with the Biden family,” he added.
