Reuters:  President Donald Trump held two campaign rallies on Wednesday in the battleground state of Arizona, where polls showed him narrowly trailing Democratic rival Joe Biden, as the White House race heads into its final five-day stretch.  Biden, who has repeatedly criticized Trump for failing to contain the coronavirus pandemic, received a briefing from public health experts and delivered a speech near his home in Delaware on his plans to combat COVID-19 and protect Americans with pre-existing health conditions, his campaign said.
 Biden still leads Trump comfortably in national opinion polls in a race dominated by the pandemic, which has caused more than 225,000 U.S. deaths, cost millions more their jobs and spurred a rush to vote early by many Americans looking to avoid health risks from exposure.
 The race is tighter in several battleground states where the election might be decided.
 More than 70 million people have cast early in-person and mail ballots
