Hunter Biden is willing to testify publicly before the Republican-led House Oversight Committee on any day in December, according to his lawyer Abbe Lowell.

In a letter sent to Oversight chairman James Comer (R., Ky.), Lowell said the president’s son will testify before the congressional panel rather than show up to a private deposition. The correspondence was written in response to House Republicans subpoenaing Hunter Biden on November 8 for a closed-door deposition as part of the GOP’s impeachment inquiry into President Joe Biden.

“We have seen you use closed-door sessions to manipulate, even distort the facts and misinform the public. We therefore propose opening the door … rather than subscribing to your cloaked, one-sided process,” Lowell wrote Tuesday in a letter.

Hunter Biden’s attorney said the first son can appear at the public hearing on December 13, or any other date next month that both sides can agree on. Comer did not immediately issue a statement in response to the letter.
