WASHINGTON, D.C. — Kamala Harris and rival Donald Trump are campaigning in battleground states Sunday seeking 11th-hour advantages in a deadlocked White House race, as new polling shows the vice president underperforming among some traditional Democratic voter demographics.

Harris was in North Carolina, a state hard-hit by a hurricane two weeks ago that devastated several communities and left more than 235 people dead across the US Southeast, as she seeks to counter Trump's claims that federal agencies have done little to help storm victims.
