Dr. Jen Peña, the personal doctor of Vice President Mike Pence, has abruptly resigned amid reports that she blew the whistle on misconduct allegations against Ronny Jackson, who was President Donald Trump's pick to run the Department of Veterans Affairs.

"The Vice President’s office was informed today by the White House Medical Unit of the resignation," Pence spokeswoman Alyssa Farah said in a statement given to Politico. "Physicians assigned to the Vice President report to the White House Medical Unit and thus any resignation would go entirely through the Medical Unit, not the Vice President’s office."

A memo written by Peña and obtained by CNN last month "accused Jackson of overstepping his authority and inappropriately intervening in a medical situation involving the second lady as well as potentially violating federal privacy rights by briefing White House staff and disclosing details to other medical providers -- but not appropriately consulting with the vice president's physician."

Additionally, according to CNN, Peña "later wrote in a memo of feeling intimidated by an irate Jackson during a confrontation over the physician's concerns."

It is unclear at this time why Peña decided to step down as Pence's personal physician.
