A Democratic delegate has been accused of trying to kill her husband, a week before she was set to back Hillary Clinton for president at the party's National Convention.

Mother-of two Denna Vicites, 47, was arrested and charged with attempted murder after she allegedly shot her other half, Vincent, in the neck during a drunken argument in their Uniontown, Pennsylvania, home on Sunday.

When she was interviewed by police, she told officers it was an accident.

But she later changed her story and said she fired at her Fayette County commissioner husband when he was choking her, claiming he had been abusive for a long time.

But then she insisted she was trying to kill herself, and then accidentally shot him when he tried to take the weapon from her, the Pittsburgh Post-Gazette reported.

Democratic Party officials say they expect to get Ms Vicites' resignation Tuesday. They say Hillary Clinton's campaign will choose a replacement.

Her husband is recovering at a West Virginia hospital.

According to a criminal complaint, the couple told officers the shooting was an accident, but investigators say they determined that Deanna Vicites tried to kill her husband.

Fayette County District Attorney Richard Bower said on Monday that the shooting was deliberate.

'This is absolutely not an accident. This is an intentional, reckless act,' he said.

State troopers said they went to the home early on Sunday when Mr Vicites called 911 to say he'd been shot.

A man who lives in the basement of the couple's home also called 911 after he said Mr Vicites pounded on his door and asked for help.

Mr Vicites apparently had returned upstairs, after which the young man said he called Mr. Vicites' cell phone and heard him yelling 'Call 911!' The witness then said he heard a shot.

His wife lying outside the front door, curled up, according to reports.

They then discovered the gun on the front lawn.

When Mr Vicites was interviewed at the hospital, troopers said he couldn't talk.

However he was reportedly able to answer questions by moving his head or writing notes.

He said the couple had argued that day and drank.

Then, he fell asleep in his chair.
