IRS whistleblower refuses to cooperate with Senate probe on mishandling of Hunter Biden case.

An IRS criminal investigator, Gary Shapley, who accused Justice Department officials of slow-walking a long-running probe into President Joe Biden’s son Hunter’s tax affairs, has cut off communication with the Senate Finance Committee amid questions about the veracity of his claims and his motivations for coming forward. Shapley is set to give evidence in a closed session before the House Ways and Means Committee on Friday. The allegations of favoritism towards Hunter Biden are consistent with grievances expressed by prominent Republicans such as Donald Trump.
