Two more of Louisiana Gov. Bobby Jindal’s top aides are leaving the governor’s office for Jindal’s presidential campaign.

CNN reports that Chief of Staff Kyle Plotkin and Jindal spokeswoman Shannon Bates Dirmann will work on Jindal’s 2016 communications staff.

Jindal is expected to formally announce his presidential run in Kenner on Wednesday.

Dirmann and Plotkin have been in the governor’s office since 2008. Plotkin started out as press secretary, eventually moving up to chief of staff.

Earlier this year, two other aides from the governor’s office were shifted to the campaign.
