Daniel Koh, a former chief of staff to Boston Mayor Martin Walsh, filed for a recount Friday in the Democratic primary for Massachusetts’ 3rd District, according to a media report.

“We want the process to progress as swiftly as possible so that the ultimate nominee will have adequate time and resources to win in November,” the Koh campaign said in a statement to the Boston Herald.
