A judge on Wednesday granted Hunter Biden's request to have his tax trial in California postpone from June to September. 

U.S. District Judge Mark C. Scarsi agreed to delay the trial until Sept. 5, citing the needs of the defendant to prepare for a June 3 trial in Delaware on federal gun charges, according to the Associated Press. 

The president's son has pleaded not guilty to each of the federal indictments. 

Prosecutors opposed the request to delay the federal tax trial, dismissing prosecutors' argument about its "high-profile" nature. 

They say it's a “straightforward tax case.”

In addition, Justice Department special counsel David Weiss’ team wrote in a recent court filing that Biden is "not above the rule of law and should be treated like any other defendant.”

Biden allegedly failed to pay at least $1.4 million in taxes over four years. However, the back taxes have since been paid, the wire service also reports.
