AUSTIN, Texas -- Texas Agriculture Commissioner Sid Miller has deleted a post on his official Twitter account that used an obscenity to refer to Hillary Clinton.

The Republican posted a purported presidential poll from Pennsylvania showing Donald Trump with 44 per cent and Clinton 43. But rather than saying Clinton, the tweet included a sexually explicit, derogatory term for women.

It was deleted about 10 minutes later. A subsequent post said "the campaign was retweeting" information and "inadvertently" posted a derogatory term. It added: "Commissioner Miller finds the term vulgar and offensive" and apologized.

A Trump supporter, Miller's Twitter bio describes himself as a "deplorable." Clinton once derided Trump supporters as a "basket of deplorables."

Last year, a later-deleted post on Miller's campaign Facebook page appeared to endorse a nuclear bombing of "the Muslim world."
