Hillary Clinton is pushing back against charges that she's physically unfit for the White House.

The Democratic presidential candidate says the accusations are part of a "wacky strategy" and an "alternative reality" that's not focused on the kinds of issues that are most important to voters.

"I do feel sometimes like this campaign has entered into an alternative universe," she says. "I have to step into the alternative reality and, you know, answer questions about, am I alive, how much longer will I be alive, and the like."

Clinton says she doesn't question GOP rival Donald Trump's health, saying he's as "healthy as a horse."

Clinton was speaking in an interview with late night host Jimmy Kimmel.

Trump promised in an interview Monday that he would deliver a "fair but firm" policy toward the 11 million immigrants living in the United States illegally.

That has raised questions about whether Trump is backtracking from previous pledges to push for mass deportations.

Republican vice presidential candidate Mike Pence is doubling down on running mate Donald Trump's call for Hillary Clinton to shut down her family's long-time charitable foundation.

Pence said Monday at a manufacturing facility in Cedar Rapids, Iowa, that Clinton must close the Clinton Foundation immediately. Trump issued the same call earlier in the day through social media.

Clinton's campaign announced recently the foundation will stop accepting foreign donations if she is elected president. Pence says that pledge isn't enough and the Democratic presidential nominee needs to "come clean" about the foundation.

Answering a question Monday in Akron, Ohio, Trump said, "I think it's ridiculous that they're not" given the equipment.

The Republican presidential nominee also said he believed that some rising crime is partly due to a decline in police manpower and vowed to change that.

Trump met with two dozen active and retired police officers at Lodge 7 of the Fraternal Order of Police. The union's national organization is expected to announce an endorsement next month.

Is a 12-year-old really running Republican Donald Trump's presidential campaign in Jefferson County, Colorado?

Broadcast reports describe Weston Imer (EYE'-mer) as running the field operation in the state's fourth most populous county. The boy's mother, Laurel Imer, is technically in charge but says she's ceded responsibility to her son until school starts.

Trump's Colorado co-chair, Robert Blaha, says while the campaign likes to have Weston speak at rallies and knock on doors, he's not the campaign office boss.

Says Blaha in an interview: "There's not the possibility a 12-year-old can run an office."

Colorado is traditionally a swing state, but polls show Democrat Hillary Clinton opening a lead over Trump. Clinton and her allies have stopped advertising in Colorado and shifted money to more competitive states.

Kaine spoke Monday in Las Vegas at the ironworkers' union annual convention.

He is also criticizing Trump's resistance to efforts by employees to unionize at his hotel off the Las Vegas strip.

Senate Minority Leader Harry Reid has launched an online petition demanding that Donald Trump take the U.S. citizenship test.

He argues that Trump would likely fail the citizenship test and that he should be forced to prove otherwise before setting rules for new immigrants to the country. Trump has called for "extreme vetting" of immigrants seeking admission to the United States.

"Donald Trump is nothing more than a spoiled, unpatriotic drain on society who has earned nothing and helped no one," Reid says in an email sent from his fundraising committee. "And before he degrades immigrant families who work hard and give up everything they knew to come to this country, he should put up — or shut up."

GOP officials insist presidential nominee Donald Trump is finally hitting his stride and will catch up with Democrat Hillary Clinton by around Labor Day.

Clinton campaign officials dismissed the idea of a changed Trump as nonsense.

Republican Party chairman Reince Priebus (ryns PREE'-bus) said Sunday that "Donald Trump has been disciplined and mature. And I think he's going to get this thing back on track."

Polls now mostly show Trump lagging Clinton by 5 percentage points or more nationally, but Priebus predicted they will tighten up and Trump will be "ahead as we move through September."

Trump's new campaign manager, Kellyanne Conway, echoed Priebus' optimism, contending that the candidate just had the best week of his campaign, "mostly because he's able to be himself, the authentic Donald Trump."
