A city council member from Texas has been forced to apologize after he sparked outrage by calling New York Rep Alexandria Ocasio-Cortez a 'bimbo' on Twitter.

Richardson City Councilman Scott Dunn responded to a tweet from the outspoken freshman congresswoman by writing: 'The embarrassment is to have bimbos like you with nothing between your ears.'

The post received enough backlash that Dunn ultimately deleted his Twitter account, but not before his comment was immortalized in a screenshot that's gone viral.

Because the post was deleted, it's unclear which specific tweet Dunn was responding to, but the Dallas Morning News reported that it was in 'defense of the president' and his State of the Union address earlier in the week.

Ocasio-Cortez, the youngest woman ever elected to Congress, has become a political lightning rod due to her staunch criticisms of the Republican Party and her socialist platform.

She has not responded publicly to Dunn's remark.

Dunn posted a brief apology to his personal Facebook page, which has since been made private.

'The words I used were offensive,' he wrote. 'I am responsible for my own words and actions. I apologize to anyone who finds what I said offensive.'

Richardson Mayor Paul Voelker released a statement saying he was 'extremely disappointed and embarrassed' to see Dunn's comment.

'While I certainly respect Councilman Dunn's, or any citizen's, right to freely express his or her opinion on any issue of public concern, I also believe that Richardson’s values are best upheld when we engage in civic discourse that is civil in tone, respectful of others and designed to produce constructive outcomes for the betterment of our community.

'Even when we disagree about important political and social issues, we shouldn’t resort to name-calling.

'I condemn the description of any woman in this manner as clearly inconsistent with Richardson's values.'

Voelker noted that Dunn's comment was not made in an official capacity or using city communication channels.

The mayor added: 'I have expressed my concerns to Councilman Dunn, and I am hopeful that he will take this matter deeply to heart and that he will express sincere remorse and a clear understanding of his words' hurtful impact.'

A candidate for Richardson city council, Mauri Long, also released a statement about Dunn's comment, which she called 'inappropriate, demeaning and divisive'.

'As one of only two women running for City Council, I find this sort of locker room talk disturbing and personally offensive,' Long wrote.

'This type of caustic rhetoric by an elected representative of our great city is not reflective of our own values.'

Dunn has served on the city council since 2011, and announced last month that he will not be running for re-election.
