Donald Trump returns Saturday for a campaign rally in North Carolina, where the former president is confronting a mess he played a key role in making in the critical battleground state.

Explosive posts by the Republican candidate for governor, Mark Robinson, are sending waves of anxiety through a state party that has long been tactical and disciplined.

More screenshots from the forum, where over a decade ago Mr Robinson signed up with his full name and a username he went by on other platforms, show the candidate describing a keen appetite for “tranny on girl porn” and sex with his wife’s sister.
