Former White House press secretary and current Fox News contributor Dana Perino is filling in for Greta Van Susteren during tonight’s “On the Record.”

Perino announced the news via her Twitter feed around 3:30 ET.

In March she served as a guest-host on FNC’s morning program “Fox & Friends.”

Update: Greta is currently in Pakistan, where she will interview Secretary of State Hillary Clinton. The interview will air tonight during “On the Record.”

Update 2: Whoops, it turns out Perino has filled in for Greta before, with her first time actually being July 5.
