Harris appeals to Christians and Arab Americans, Trump embraces violent rhetoric

This combination of photos shows Democratic presidential nominee Vice President Kamala Harris, left, speaking during a rally in Charlotte, N.C., September 12, and Republican presidential nominee former President Donald Trump, right, speaking during a rally in Warren, Mich., November 1

Democrat Kamala Harris made her closing pitch for the US presidency at a historically Black church and to Arab Americans in battleground Michigan on Sunday, while her Republican rival Donald Trump embraced violent rhetoric at a rally in Pennsylvania.

Opinion polls show the pair locked in a tight race, with current US vice president Harris, 60, bolstered by strong support among female voters while former US president Trump, 78, gains ground with Hispanic voters, especially men.
