WASHINGTON (AP) — The Latest on the 2016 presidential campaign (all times EDT):
Former President Bill Clinton, appearing on behalf of his wife and Democratic presidential nominee Hillary Clinton, will address thousands of Asian-American and Pacific Islander voters at a forum in Las Vegas.
Libertarian presidential candidate Gary Johnson will also speak at the gathering Friday at the Colosseum at Caesars Palace.
Billed as the 2016 Presidential Election Forum, the event is being put on by the Asian American Journalists Association and the Asian and Pacific Islander American Vote.
Organizers say they are in the final stages of discussions with Republican nominee Donald Trump's campaign.
The forum will mark the first time major presidential campaigns speak directly to the AAPI community at the same event.
Members of the Congressional Asian Pacific American Caucus also plan to talk about the importance of voting.
Vice President Joe Biden seems to be taking a swipe at Donald Trump for the candidate's recent remark that he "always wanted to get the Purple Heart."
On Twitter Sunday, Biden wrote: "No one wants to earn a Purple Heart. But to those who did, you have America's unending gratitude and admiration. Thank you. #PurpleHeart Day."
The Purple Heart acknowledges service members who have been wounded or killed. At a voter rally in Virginia, Trump accepted a Purple Heart from an audience member by saying he always wanted one but "this was much easier."
Newt Gingrich says that "of course" Donald Trump's economic plan doesn't add up and adds that historically, no candidates' numbers do.
The former House speaker and presidential candidate was responding to a question on FOX News Sunday about whether Trump's plan to slash corporate and other taxes was economically sound.
Gingrich replied, "Of course not....No candidate's numbers add up."
Gingrich quickly suggested ways how Trump's plan might offset the loss of government revenue if he cuts corporate tax from 35% to 15%, as Trump plans. Gingrich said Trump could offset tax losses by overturning Obama administration regulations and from expanded energy exploration revenues.
Trump and Clinton are expected to outline their economic plans this week in Detroit.
Some Republicans are giving their presidential candidate positive reinforcement for reversing himself and endorsing House Speaker Paul Ryan, Sen. John McCain and Sen. Kelly Ayotte.
Former House Speaker Newt Gingrich said Trump "should have done that in the first place," but has "gotten the messages" from other Republicans to unify the divided GOP. He suggested that Trump is climbing a learning curve in his transition from business world titan to presidential candidate.
Former New York City Mayor Rudy Giuliani says Trump's endorsements, coming after his refusal to endorse the trio, show that Trump "has the ability and the understanding to realize that there are going to be disagreements and you've got to be able to reach out to the entire party."
Gingrich spoke on "Fox News Sunday." Giuliani spoke on ABC's "This Week."
Ohio Gov. John Kasich says he has no idea how he'll vote come November because he doesn't support Donald Trump or Hillary Clinton. He also says he isn't sure whether Trump can win Ohio if he remains so divisive.
Kasich, who lost the GOP primary to Trump and shunned the Republican National Convention, tells CNN's "State of the Union" that four years of Hillary Clinton would mean "total gridlock."
But Kasich says he can't swing behind Trump either, and that any candidate who wants to win his support has to "operate in the light," and not on the "dark side of the street."
As secretary of state, Hillary Clinton basked in a diplomatic "Moscow Spring," seizing on Vladimir Putin's break from the presidency to help seal a nuclear arms-control treaty and secure Russia's acquiescence to a NATO-led military intervention in Libya.
But when Putin returned to the top job, things changed.
Now the Democratic presidential nominee, Clinton has vowed to stand up to Putin if elected, drawing on her four years of ups and downs as the public face of President Barack Obama's first-term "reset" with Russia. By comparison, her Republican opponent, Donald Trump, has rung alarm bells in Washington and Europe with his overtures to the authoritarian Russian leader.
But Clinton's wrangles with Russia led to mixed results.
Democratic presidential nominee Hillary Clinton will deliver what aides are billing as a major economic speech on Thursday in Detroit.
Clinton's appearance is set to follow a speech planned by Republican rival Donald Trump on what he would do to improve economic growth. Trump's speech is set for Monday in the same city.
The dueling Detroit addresses come as new polls show Clinton gaining ground on economic issues.
Aides say Clinton will outline her economic plans and argue that Trump is only focused on the wealthiest Americans.
At campaign events last week, Clinton questioned Trump's commitment to creating American jobs by highlighting his use of outsourcing at his companies.
Trump's populist economic message includes a vow to revive manufacturing jobs and renegotiate trade deals to benefit American workers.
