Kamala Harris and Donald Trump have been ramping up personal attacks on each other as the White House rivals blitzed battleground states 16 days before the election.
In Pennsylvania, Trump served fries at a McDonald’s as he sought to cast doubt on Harris’s biographical detail about having worked decades ago at the fast-food chain.
The US vice-president was in Georgia, where she tweeted that Trump was “exhausted, unstable, and unfit to be President of the United States”.
Polls show the two locked in a razor-tight race across the country, including in the seven battleground states that could swing the election.
Speaking in Lancaster County on Sunday, Trump focused on economic issues and the US border issues which his campaign believes give him an edge with undecided voters.
