President Biden's son Hunter Biden will be indicted in California, Fox News has learned. 

While the exact nature of the charges remain unclear, the indictment in the Central District of California was expected later Thursday. 

Special Counsel David Weiss has been using a federal grand jury in Los Angeles to gather evidence of possible criminal tax charges against Hunter Biden. 

Hunter Biden pleaded not guilty in October to federal gun charges in U.S. District Court for the District of Delaware after being charged out of Weiss' years-long investigation. 

HUNTER'S EX-BUSINESS ASSOCIATE BLASTS BIDEN'S NEW CLAIM ABOUT SON'S BUSINESS DEALINGS

Fox News Digital has reached out to Hunter Biden's legal team for comment. A spokesperson for Special Counsel Weiss declined to comment. 

Thursday's development comes ahead of an expected vote from House Republican leaders next week on a measure that would formally initiate an impeachment inquiry into President Biden over possible ties to his son's business dealings. 

Earlier this week, House Oversight Committee Chairman James Comer, R-Ky., released subpoenaed bank records showing an entity owned by Hunter Biden had made "direct monthly payments to Joe Biden." 

The White House has repeatedly said that President Biden did nothing wrong and had no knowledge of his son's business dealings. 

House Republicans, meanwhile, have warned the younger Biden they would move to hold him in contempt of Congress if he didn't appear for a closed-door deposition on Dec. 13. 

Hunter Biden has insisted he would only testify to the House if it's in public because information from closed-door testimonies is selectively leaked and used to "manipulate, even history, the facts and misinform the American public."
