The Kentucky congressman who will lead Republican investigations if the GOP takes back the House in 2022 is lining up Hunter Biden and the 'Biden crime family' as one of the main targets.

Rep. James Comer, who is primed to take over as chairman of the Committee on Oversight and Reform, says the president's son and his business associates have many questions to answer over his foreign deals and taxes.

He says the White House will also be pressed on whether the president knew about any of the transactions and believes American voters are now coming around to the fact the Hunter scandal isn't a 'conspiracy theory' and are questioning the administration's ethics and transparency.

Comer called Hunter a 'national security risk' and a 'grifter' who has built his 'business model' on 'selling access to his father', and believes Democrats see him as an issue leading up to the midterms.

Outgoing press secretary Jen Psaki has consistently denied Biden has spoken to his son about his business deals and has referred to the Department of Justice when asked about the investigation in Delaware into tax offenses, money laundering and illegal lobbying for foreign clients.

She has also declined to answer questions on the basis he doesn't work for the Biden administration.

The Republicans are currently the minority in Congress, but dismal polls and mounting issues for President Biden and the Democrats point to them taking back at least the House in the November midterm elections.
