WASHINGTON (AP) — The Latest on the 2016 presidential campaign (all times EDT):
Mike Pence has received his first national security briefing since becoming Donald Trump's running mate.
Pence's briefing Friday lasted about two hours and was held at an Indiana National Guard base in Indianapolis.
The Republican Indiana governor said afterward that he was "grateful" for the "thorough and informative" briefing.
Pence said he couldn't discuss specifics due to classified nature, but vowed that he and Trump would be "ready on day one" should they be elected in November.
He did not take questions afterward, but said he was honored to take part in the tradition, which he says extends back to the time of Harry Truman.
The Republican Party is storming into what it sees as 11 presidential battleground states on Saturday.
About 1,000 employees and 4,000 volunteers will be knocking on doors to speak with voters in states including Ohio, Wisconsin and Virginia. The Republican National Committee expects to hit more than 450,000 doors in a single day.
The party will promote its presidential nominee Donald Trump and other Republican candidates for office. Door knockers will focus on voter registration and in places such as Florida and Iowa, will urge voters to request absentee ballots as a way to ensure more votes.
The all-day event follows what the RNC dubbed its "month of action" in August. Party leaders say they knocked on 2 million doors, more than in July and June combined.
Minnesota Democrats are asking the state's Supreme Court to remove Republican presidential nominee Donald Trump from the ballot.
The state party filed a petition Thursday seeking to have Minnesota's secretary of state strip Trump and running mate Mike Pence from the ballot for the general election.
They argued that the Republican Party of Minnesota erred in how it sent in Trump's name for a spot on the ballot.
State law requires political parties to select alternate electors at conventions as part of putting a nominee on the ballot, and the clock is ticking for a resolution. Early voting in Minnesota begins Sept. 23.
But Democrats contend those GOP alternates were chosen last-minute by party leaders to meet a looming deadline last month. The state's Democratic party says that invalidates the GOP's ballot submission and that Secretary of State Steve Simon should have rejected it.
The number of retired generals and admirals endorsing Hillary Clinton for president has grown to 110.
The Democratic presidential nominee announced her newest supporters Friday. Clinton stressed that she has more military backing than rival Donald Trump, who touted endorsements from 88 retired U.S. generals and admirals earlier in the week.
The new endorsements include former Democratic Pennsylvania congressman Joe Sestak, a retired Navy admiral.
Clinton is continuing to promote herself as the best choice for commander-in-chief, questioning Trump credentials and judgment. On Friday afternoon, she plans to meet with foreign policy and national security experts in New York City to discuss ways to combat terrorism.
Hillary Clinton is now opting to mark the fifteenth anniversary of the September 11 terror attacks with a visit to ground zero.
A spokeswoman for Clinton confirmed the visit to The Associated Press on Friday.
Clinton, who was a U.S. senator from New York in 2001, was not initially scheduled to visit the memorial site on the anniversary. But her campaign notified officials at the National September 11 Memorial & Museum late Thursday that she would attend the morning's events.
Her Republican rival, Donald Trump, is currently not slated to attend.
Clinton is not expected to make any public remarks but wanted to honor the attacks' victims.
Both candidates previously pledged to avoid campaigning on the somber anniversary.
Democratic vice presidential nominee Tim Kaine is doing his share of fundraising to help fuel the final push toward Election Day.
Hillary Clinton's campaign said five people paid up to $500,000 each to attend a fundraiser with Kaine in New York on Thursday night. That's one of four fundraisers Kaine attended in New York that day. He did not do any public events.
He met with approximately 120 people who paid either $5,000, $10,000 or $50,000.
Kaine on Wednesday met with donors twice in Washington, D.C., and once in Potomac, Maryland. On Tuesday he raised money in Chapel Hill, North Carolina.
Kaine will raise money and campaign Friday in Birmingham, Alabama and attend a public event in Norfolk, Virginia.
Democratic vice presidential nominee Tim Kaine says Donald Trump "demonstrates an irrational hostility" toward President Barack Obama.
In an interview with CBS "This Morning" Friday, the Virginia senator said Trump's comments favoring Russian President Vladimir Putin over Obama are "unpatriotic."
He said that Putin has invaded other countries, run the Russian economy "into the ground," and persecuted Russian journalists and members of the gay and lesbian community.
He said, "you wouldn't get out of a fifth grade civics exam if you don't understand the difference between dictatorship and leadership," referring to the Republican nominee.
Donald Trump's campaign manager says if he's president and North Korea fired ballistic rockets, Trump "wouldn't do what's done now."
Kellyanne Conway told CBS's Charlie Rose Friday that Trump's position is to put America first, but she offered no details for how the Republican nominee would handle North Korea's growing nuclear threat.
North Korea conducted its fifth nuclear test on Friday, just eight months after it claimed it successfully detonated a small hydrogen bomb. It was the first time the Asian nation conducted two nuclear tests in one year.
Conway said that if Trump is president, North Korea will know that the Americans "aren't messin' around."
Voting in the 2016 election is getting underway.
Advance voting is beginning Friday in North Carolina — the first of 37 states that will allow balloting by mail for any reason or in person before Election Day, which is Nov. 8.
It's part of a nearly nine-week campaign frenzy during which millions of voters will have the ability to fill out a ballot for the 2016 presidential race.
Data compiled by The Associated Press shows that people who vote in advance are expected to make up between 50 percent to 75 percent or more of all ballots in some of the race's most pivotal states — North Carolina, Colorado, Florida, Nevada, Arizona and Georgia.
A billionaire Facebook co-founder says he's giving $20 million to help defeat Donald Trump.
Dustin Moskovitz says the Republican presidential nominee is divisive and dangerous. And he says Trump's appeals to people who feel left behind are, in Moskovitz's words, "quite possibly a deliberate con."
By contrast, he says Democrats and nominee Hillary Clinton are running on what he says is "a vision of optimism, pragmatism, inclusiveness and mutual benefit."
Moskovitz wrote about the contributions in a Thursday night posting on the website Medium.
He and his wife, Cari Tuna, are giving half of the $20 million to the League of Conservation Voters and to the For Our Future political action committee.
That second latter group is a get-out-the-vote effort in battleground states. It's paid for primarily by labor unions and hedge fund billionaire Tom Steyer.
