US presidential candidates Kamala Harris and Donald Trump have returned to battleground state Wisconsin, four days before election day. Both had earlier campaigned in the western part of the US, holding rallies in the key swing states of Arizona and Nevada. Ms Harris topped last night with a performance by celebrity Jennifer Lopez in Las Vegas, as she sought to connect with Latino voters in the final days of the race. Mr Trump, meanwhile, appeared with far-right media personality Tucker Carlson in Phoenix. Caroline Malone reports.
