Hunter Biden criticised "absurd" claims about his father Joe Biden on Wednesday, 13 December, as he defied a congressional subpoena to appear privately for a deposition before Republican investigators who have been digging into his business dealings. "In the depths of my addiction, I was extremely irresponsible with my finances. But to suggest that is grounds for an impeachment inquiry is beyond the absurd," Hunter said. It comes as the Republican-led House moves forward with a vote to formalise an impeachment inquiry into the president, with three committees alleging bribery and corruption during Mr Biden's time as vice-president.
