Harris’s convention speech sparks live rant from outraged Trump

Ex-president's 48 posts during speech confirm his trouble in maintaining discipline on the campaign trail

Kamala Harris's Democratic national convention speech provoked a torrent of outrage from Donald Trump as the former US president fired off a volley of ripostes, rebuttals and angry calls to TV stations.

Trump posted 48 times on his Truth Social network during Harris's 37-minute presidential acceptance speech, which was nearly an hour shorter than his own effort at the Republican convention last month.
