Labor MP Emma Husar is suing media site Buzzfeed and journalist Alice Workman for publishing what she says were slut-shaming smears that she was not given opportunity to respond to before they went viral.

Clearly emotional, Ms Husar gave a personal explanation to Parliament as the sittings came to a close for the year. She did not say whether she would fight the Labor Party to retain endorsement to contest her western Sydney seat at the next election, amid speculation she could also quit and run as an independent.

Ms Husar said Buzzfeed had only approached her for a response to 48 questions one minute after the article was published. "I had no chance to refute, nor respond."

Ms Husar said Buzzfeed claimed she had bragged about her sexual relations, sexually harassed an employee and exposed herself to a colleague and his infant son. "I am not a bully, I am not Sharon Stone, I am not a thief and I did not deliberately misuse my work expenses," she said, referencing the Hollywood star widely associated with a sexually graphic film scene.
