Presidential election campaigning revs back up Tuesday, with Donald Trump heading to Michigan and Vice President Kamala Harris answering questions at a forum for Black journalists in Pennsylvania - even as authorities continue to investigate a second apparent assassination attempt against Trump that's roiled the race.
Trump is holding a town hall in Flint, Michigan, and has appearances later in the week in New York, Washington and North Carolina. Harris will participate in a Philadelphia gathering of the National Association of Black Journalists . She skipped the group's recent gathering in Chicago, but an openly antagonistic appearance there by Trump sparked an uproar when he questioned the vice president's racial identity .
Harris has her own stops in Washington, as well as Michigan and Wisconsin, planned in coming days, with both sides zeroing in on the industrial Midwest and Pennsylvania and North Carolina - all battleground areas that could swing an election expected to be exceedingly close.
Trump has claimed, without evidence, that months of criticisms against him by Harris and President Joe Biden inspired the latest attack . That's despite the former president's own long history of inflammatory campaign rhetoric and advocacy for jailing or prosecuting his political enemies .
Both Biden and Harris have so far avoided politics in reacting to the attack. Harris has condemned political violence while Biden has called on Congress to increase funding to the Secret Service.
