VP and Trump are making frequent stops in state, with Harris visiting two days after visiting US-Mexico border

Kamala Harris held a rally in Las Vegas on Sunday night as the state, with six electoral college votes, becomes increasingly important in a presidential race that polls show is barely moving to favour either candidate.

Both the vice-president and Donald Trump have been making frequent trips to Nevada, but Harris’s rally takes place two days after she visited the US-Mexico border, a vulnerable issue for Democrats that Harris is looking to defuse.
