Kimberly B. Morton, a holdover from the Rawlings-Blake administration, has been offered the job of chief of staff by Mayor Catherine Pugh, sources tell The Brew.

The offer was made as the mayor searches for a successor to Tisha Edwards, who is stepping down as the mayor’s right-hand aide after five months.

Morton was deputy chief of staff under former Mayor Stephanie Rawlings-Blake, paid a salary of $140,000 a year to assist the powerful chief of staff, Kaliope Parthemos.

When Pugh became mayor, Parthemos was let go, but Morton was retained as deputy chief of operations under former state Delegate Peter Hammen.

Known for her aggressive style, Morton has been in city government for nearly 13 years. She served as chief of staff at the Department of Public Works prior to being tapped by Parthemos, who replaced Alexander M. Sanchez in May 2014 as the fourth chief of staff under Rawlings-Blake.

Edwards is expected to remain as chief of staff until at least mid-May.

Pugh’s spokesman, Anthony McCarthy, could not be reached for comment tonight.

5/3 UPDATE: At her weekly press conference, Pugh said that she has not yet settled on a new chief of staff and declined to comment further.
