Trump concludes MSG rally with anti-immigrant rhetoric

In what could have been his final financial event of the campaign, Tim Walz, at a fundraiser in Pennsylvania, said it was now time to use all that money to focus on the ground game.

"Now it's time to execute ... Never in my lifetime, would I have believed that the choice would be so stark," he said.

The Harris campaign and the Democratic National Committee entered the final three weeks of the election with a clear cash advantage over the Trump campaign and the Republican National Committee, latest FEC records show.

As of Oct. 16, the Harris campaign, the DNC and their joint fundraising committees reported having nearly $270 million in cash on hand compared to $202 million the Trump campaign, the RNC and their joint fundraising committees had in the bank, the new filings show.

The Trump campaign committee, in particular, had $36 million in the bank as of Oct. 16 compared to the Harris campaign committee having $119 million in cash on hand.

Trump on Friday reposted his earlier message promising, before any evidence of fraud, to prosecute and deliver long prison sentences for election workers and others who he deems to have cheated during November's election.

"Please beware that this legal exposure extends to Lawyers, Political Operatives, Donors, Illegal Voters, & Corrupt Election Officials," Trump wrote on his social media platform. "Those involved in unscrupulous behavior will be sought out, caught, and prosecuted at levels, unfortunately, never seen before in our Country."

Election officials had called such a threat "dangerous" given the heightened threat environment.

"It makes me concerned that this will set other people off. I think the one thing that we've seen before is that words have consequences and meaning," Arizona Secretary of State Adrian Fontes told ABC News last month.

"And while we are concerned, we are also prepared. Elections officials across the country have been working with local, state and federal law enforcement agencies to monitor and track threats, to make sure we're keeping our voters safe and make sure we're keeping our elections officials safe," Fontes said.

Harris, taking reporter questions on Friday, was asked if she's cast her ballot yet.

Her running mate, Gov. Tim Walz, voted with his wife and son in Minnesota earlier this week.

Harris said she hasn't voted but "it's on my priority list for these next few days."

Trump is attempting to place doubt about voter rolls in Virginia after a judge ordered voters purged from election rolls as a result of Gov. Glenn Youngkin's directive to be reinstated.

A federal judge said on Friday Youngkin's program violated the National Voting Rights Act of 1993.

"This is a totally unacceptable travesty, and Governor Youngkin is absolutely right to appeal this ILLEGAL ORDER, and the U.S. Supreme Court will hopefully fix it! Only U.S. Citizens should be allowed to vote. Keep fighting, Glenn - AND REPUBLICANS IN VIRGINIA, KEEP VOTING EARLY!" Trump posted on his social media platform.

Republican National Committee co-chair Lara Trump is set to rally with Youngkin on Saturday. Trump said he plans to call into the rally to highlight the issue.

"I will be calling in to Glenn's Rally with Lara Trump tomorrow morning to talk about this crazy Ruling, and announce my final stop in Virginia before Election Day."
