Malvern, Pennsylvania - Democratic presidential candidate Kamala Harris made a push to woo moderates in three swing states Monday, while Republican Donald Trump slammed the government's response to Hurricane Helene as he toured the devastated state of North Carolina.

With just over two weeks until Election Day, the Democratic vice president and her Republican opponent are on a blitz through the battlegrounds that will decide the outcome in a race that polls say is too close to call.

On Monday, Harris appeared in Pennsylvania alongside Liz Cheney – a prominent Republican – who called on undecided voters "to reject the kind of vile vitriol that we've seen from Donald Trump."

Trump toured storm-damaged Asheville and repeated conspiracy theories about the government's disaster response. Later, at a rally in Greenville, he hammered home his campaign message that immigrants were "looting, ransacking, raping, and pillaging" the country.

On Monday alone, Harris had events scheduled in Pennsylvania, Michigan, and Wisconsin – Rust Belt states that were in Trump's column in 2016 but crucial to President Joe Biden's victory four years later.

Harris said Trump's dominance in politics since his shock 2016 election had led Americans to "point the finger at one another" and left the country "exhausted."

"Donald Trump is an unserious man, and the consequences of him ever being president of the United States again are brutally serious," she said.

Cheney, who along with her former vice-president father Dick endorsed Harris last month, said it was not a difficult decision to make, as a politician or as a mother.

"If you wouldn't hire somebody to babysit your kids, like you shouldn't make that guy the President of the United States," she said.

Speaking in Michigan, Harris called for voters to put partisan politics aside when they cast their ballot.

On "some issues we just have to all be Americans," she said.

Both candidates have courted voters from blocs that have historically sided with their rivals.

On Monday, Trump appealed to Arab Americans in a social media post, calling Harris a "war hawk" over the White House's continued support for Israel's brutal assault on Palestine and Lebanon.

Trump has previously cast himself as Israel's "protector" and said the government of Benjamin Netanyahu must "finish the problem" in its attacks on Gaza.

The Biden-Harris administration's refusal to end weapons transfers to Israel may spell trouble for Democrats this cycle.

Groups like the Abandon Harris Campaign and American Arab and Muslim Political Action Committee have endorsed Green Party presidential nominee Dr. Jill Stein, while polling data released last month by the Council on American-Islamic Relations pits Stein ahead of Harris among Muslim voters in several key swing states, including Michigan.

Trump has been criticized for a tumultuous few weeks that have featured rambling monologues and threats about weaponizing the military against Democrats, whom he calls "the enemy from within."

In Greenville, he painted a picture of a US that was "crippled and destroyed" by immigration, crime, and inflation.

Earlier, in Asheville, the 78-year-old doubled down on conspiracy theories, accusing the administration of redirecting disaster funds to bring in undocumented immigrants and bolster Democratic votes.

Officials in the state were forced to issue hurricane response fact-checks after Trump and his backers pushed what Biden called "an onslaught of lies" about the response.

Trump notched his narrowest victory in North Carolina in 2020, when he lost the presidential election to Biden.

Both Harris and Trump are fighting to lock down a few thousand wavering voters in key districts as they bid to edge ahead in the race.

Harris' campaign brought in and spent more than $200 million in September – more than three times as much as Trump, who is out on bail in two criminal cases and awaiting sentencing in a third over allegations of 2020 election-related misconduct.

Despite the vice president's spending, polls suggest the race has been tied since late August.

As the pair make their closing arguments, a new Washington Post-Schar School poll of registered voters in seven battleground states found support even at 47% for each candidate. Harris had a one-point lead among likely voters.

Pro-Trump tech mogul Elon Musk has weighed heavily on the election, pouring $75 million into his political committee, turning his social media company X into a bullhorn for the Republican side, and stumping for Trump in Pennsylvania.

But the state's Democratic governor, Josh Shapiro, suggested authorities could investigate Musk's promise at a weekend rally to award a $1-million prize daily until Election Day to a person who has signed an online petition "supporting the US Constitution."
