Biden, Harris to visit two key swing states devastated by Hurricane Helene

US President Joe Biden and Vice President Kamala Harris will on Wednesday visit areas devastated by the deadly Hurricane Helene, after Harris's election rival Donald Trump turned their handling of the disaster into a political football.

Biden, 81, will visit North Carolina, where he will make a helicopter trip over the flood-hit city of Asheville, one of the places worst hit by the storm's deadly rampage through the southeastern United States.

He will also visit a rescue command center in the state, where over 70 people were killed, and travel to neighbouring South Carolina, AFP reported.

Officials say Helene has killed at least 155 people and left up to 600 unaccounted for across several states.

Meanwhile, Harris, 59, who replaced Biden as the Democratic presidential nominee for the November 5 election, will travel separately to the southern state of Georgia, which has also been badly hit by the storm.

North Carolina and Georgia are also two of the seven crucial swing states that could decide the result of the election.

Biden said that he had not been able to travel earlier because rescue workers said his visit would have affected operations on the ground. He will also travel to Florida and Georgia in the coming days, the White House said.

"My top priority is to ensure the communities devastated by this hurricane get the help and support they need as quickly as possible," Biden told reporters Tuesday.

Republican former president Trump, 78, has however sought to make political capital out of the disaster, accusing the US government, without evidence, of ignoring the crisis and denying help to his supporters.

He also criticised Biden and Harris for being out of Washington over the weekend after the hurricane hit. He accused Biden of "sleeping" at his beach home in Delaware while Harris was at campaign fundraisers on the US West Coast.

Trump meanwhile made his way to the disaster zone on Monday, visiting the stricken town of Valdosta in Georgia. He vowed to "bring lots of relief material, including fuel, equipment, water, and other things."
