Vice President JD Vance's chief of staff is set to depart his role, Fox News Digital learned Thursday.

Jacob Reses is set to formally leave his role by the end of summer. Reses worked with Vance for years and played a key role in Vance's 2022 Senate campaign.

"Jacob’s been by my side for my whole career in public life. I can’t imagine having been on this life-changing journey without him. From day one of my time as a Senator-elect, I could not have asked for a more loyal and discerning advisor and friend as my chief of staff. I’ll miss him dearly, but he won’t be far, and I plan to keep his counsel close until our paths cross again," Vance said in a statement to Fox News Digital.
