Lawyers representing Hunter Biden threatened to subpoena US President Joe Biden to testify in court if the Justice Department pursued charges against his son, a Politico report suggested.

In a letter from Hunter Biden's lawyer, Chris Clark, it was indicated that President Biden could have been considered a fact witness for the defense in any potential criminal trial involving his son.

This response came after reports emerged in October 2022 that Hunter Biden might face charges related to purchasing a firearm while being an illegal drug user.

The letter stated that over 300 documents and emails were exchanged between Clark and government prosecutors. It also argued that prosecuting Hunter Biden could be interpreted as a political move and might raise constitutional concerns, particularly regarding the Second Amendment's right to bear arms.

Furthermore, reference was made to a recent US Supreme Court ruling suggesting that laws preventing drug users from owning firearms could be deemed unconstitutional.

While the Justice Department initially pursued a plea deal to resolve misdemeanor tax offenses and a pre-trial diversion agreement to address the firearm charge. These arrangements were rejected by a US judge, leading to an impasse between Hunter's legal team and government prosecutors. As a result, the possibility of a trial looms.

In addition to the legal case, US House lawmakers are investigating potential criminal activities involving the Biden family, such as foreign bribery and influence peddling. President Biden has denied involvement in his son's foreign business deals and has refrained from commenting on the ongoing case. Recently, Clark requested to withdraw from defending Hunter Biden due to the potential need for his own testimony in upcoming legal proceedings.
