Massachusetts cop accidentally sends tweet from official account calling Joseph Kennedy III a 'liberal f*****g jerk' after he called national PPE response 'embarrassing' (5 Pics)

A Boston area police officer went rogue by posting a profanity-laced tirade against Democratic Congressman Joseph Kennedy III using the force’s official Twitter account.

The Cambridge Police Department apologized on Sunday after one of its officers mistakenly tweeted angry messages about Kennedy on its official Twitter feed instead of their own personal account.

‘Another liberal f*****g jerk who just happens to be better than the clown he's running against. Sad for us,' the tweet from Cambridge police read.

The tweet was posted in response to a WCVB-TV story quoting Kennedy who was criticizing the ‘embarrassing’ state of distribution of personal protective equipment to health care professionals during the coronavirus pandemic.

House Rep. Joseph P. Kennedy III (seen above in Newton, Massachusetts, on February 24) was called a 'liberal f*****g jerk' on the official Twitter feed of the Cambridge Police Department

An officer apparently meant to post the tweet on his personal account yet accidentally sent the message using the official Cambridge Police Department Twitter feed

The ‘clown’ referenced in the tweet is Senator Ed Markey of Massachusetts.

Kennedy, 39, is challenging the 73-year-old Markey for his Senate seat this November.

‘Earlier this afternoon, a member of the Cambridge Police, who has access to the Department’s Twitter account, inadvertently posted political commentary on the department account rather than their personal account, that was inappropriate, unprofessional and disrespectful,’ the department tweeted on Sunday.

‘While the post was quickly removed, the concerning statements cannot be erased.

‘These actions do not reflect the professionalism that we as a department take great pride in and we want to sincerely apologize to the Congressman and those individuals the statement was directed at.

CPD posted a series of tweets explaining what happened on Sunday

The police department said that it had apologized to Kennedy and Senator Ed Markey

The department also pledged that it would 'take appropriate action in response to this regrettable incident'

‘The department will take appropriate action in response to this regrettable incident.’

It was unclear what action would be taken. The department declined to identify the officer who posted the tweet.

DailyMail.com has reached out to both Markey and Kennedy for comment.

Cambridge Police Commissioner Branville G. Bard Jr has personally reached out to both Markey and Kennedy’s offices to apologize on behalf of CPD, according to The Harvard Crimson. 

Kennedy is the son of Joseph P. Kennedy Jr, the eldest son of Robert F. Kennedy and his wife, Ethel, and the nephew of the late President John F. Kennedy.

Senator Ed Markey (seen above in Boston on March 15) was also called a 'clown' in the tweet. Kennedy, 39, is challenging the 73-year-old Markey for his US Senate seat in November

Joseph Jr also served as a member of the House of Representatives, representing Massachusetts' eighth congressional district between 1987 and 1999.

Joseph III currently represents the Bay State's fourth congressional district that encompasses Boston's suburbs to the west and south.
