An attorney for Hunter Biden told House Republican committee chairs on Friday that he will comply with subpoenas demanding his deposition if they issue a new one — a reversal of his prior demand that such testimony be given at a public hearing.

The surprising offer came two days after two House committees passed resolutions urging that the son of President Joe Biden be found in contempt of Congress for defying previous subpoenas.

Hunter Biden showed up at the hearing of one of those panels before it voted, silently staring down GOP lawmakers who want to depose him for an inquiry into President Biden’s possible impeachment.

A full House of Representatives vote on the contempt resolutions had been expected next week. But Hunter Biden’s new offer to be deposed could change that.

If Biden is found in contempt of Congress, the Department of Justice would consider whether to prosecute him for failing to comply with the prior subpoenas.

In his letter Friday, Biden’s attorney Abbe Lowell told two House Republican committee chairmen that those prior subpoenas were legally invalid.

But, Lowell added, “If you issue a new proper subpoena, now that there is a duly authorized impeachment inquiry, Mr. Biden will comply for a hearing or deposition.”

“We will accept such a subpoena on Mr. Biden’s behalf.”

Lowell’s offer came at the end of an eight-page letter criticizing House Oversight Chairman James Comer, R-Ky., and Judiciary Chairman Jim Jordan, R-Ohio, for passing their contempt resolutions despite Biden’s insistence that he was willing to testify in public.

“You proceeded with a contempt process, erroneously claiming Mr. Biden was seeking ‘special treatment,’ despite Mr. Comer’s repeated and public statements about witnesses’ and Mr. Biden’s ability to testify at a deposition or hearing at their choice,” Lowell wrote.

Lowell has argued that a public hearing would prevent Republicans from taking Biden’s testimony in private only to later distort or mischaracterize what he said in statements to the media or elsewhere.

The attorney told Comer and Jordan that he was writing the letter to “make you aware … that your subpoenas were and are legally invalid and cannot form a legal basis to proceed with your misdirected and impermissible contempt resolution.”

The impeachment probe centers on allegations that Joe Biden’s family members, with the president’s involvement, were corruptly exploiting his political status and power for personal financial gain. The Bidens and the White House have rejected any suggestion of “influence peddling” and have denied wrongdoing.

Hunter Biden is currently facing criminal charges in two federal courts.

On Thursday, he pleaded not guilty in U.S. district court in Los Angeles to nine criminal counts related to his failure to pay his taxes on time. The judge in that case tentatively scheduled the trial to begin on June 20.

Biden previously pleaded not guilty in Delaware federal court to charges related to having a handgun while being a drug user.
