Donald Trump’s decision to change definitions of domestic violence and sexual assault has rolled back women’s rights by half a century, campaigners have warned.

The Trump administration quietly changed the definition of both domestic violence and sexual assault back in April but the move has only just surfaced.

The change could have significant repercussions for millions of victims of gender-based violence.

The Trump Justice Department’s definition only considers physical harm that constitutes a felony or misdemeanour to be domestic violence – meaning other forms of domestic violence such as psychological abuse, coercive control and manipulation no longer fall under the department’s definition.
