The following sentence is a news report of the Hill.
Greene is facing blowback from Democrats off the heels of a Washington Post report that she harassed Ocasio-Cortez on Wednesday and shouted at her as the two left the floor.
I know what 'on the heels of' means but can't find the meaning of 'off ...' in dictionaries. I think 'on ...' makes sense too in the sentence but it doesn't seem to be a typo.
Because 'on ...' means following right after may I guess that 'off ...' is following a little behind?
