WASHINGTON (AP) — The Latest on the U.S. presidential race (all times EDT):
Florida's election officials say no credible threat to elections has been reported this year.
Chris Chambless, the president of the group representing the state's election supervisors, said in a letter posted online Monday that most voters in Florida use a paper ballot that could be used if there was a disruption in vote counting.
GOP presidential nominee Donald Trump last week said in an appearance that the election may be "rigged." Additionally there has been speculation about whether voting systems are vulnerable to cyberattacks.
Florida has overhauled its voting systems twice since the chaotic presidential election of 2000.
Hillary Clinton is replying to Donald Trump's economic address on Monday by saying it would benefit rich corporations and the wealthiest Americans at the expense of the working class. She's promising to raise taxes on the wealthy because, she says, "that's where the money is."
During a campaign swing through St. Petersburg, Florida, Clinton wryly advised her supporters: "Don't let a friend vote Trump."
Clinton says his scripted speech amounts to Trump scrambling to do "damage control" with a steadier performance designed to reassure Republicans who had grown nervous after a disastrous week.
She says, "Don't be fooled," adding, "There is no other Donald Trump."
Clinton is expected to deliver an economic address in Detroit on Thursday. Aides are billing the speech as a response to Trump's remarks.
Hillary Clinton says she will meet with health professionals combatting the Zika virus in Florida.
Speaking at a rally in St. Petersburg Monday, Clinton said she would be visiting people working on the "front line of Zika" on Tuesday.
She added that, "Washington cannot keep ignoring the needs of the families of Florida."
The Republican-controlled Congress left town in mid-July for a seven-week recess without approving any of the $1.9 billion that President Barack Obama requested in February to develop a vaccine and control the mosquitoes that carry the virus.
Abortion politics played a central role in the impasse.
A group of 50 former GOP national security officials has signed an open letter opposing Republican presidential nominee Donald Trump. Those who signed worked for former Presidents Richard Nixon, Ronald Reagan, George H.W. Bush and George W. Bush and say they are convinced that Trump would be "the most reckless president in American history."
The letter is similar to one issued by some of the same Republican former officials and foreign policy experts in March. The letter released Monday does contain some new names, however, including former U.N. Ambassador John Negroponte, former CIA director Michael Hayden and former Secretary of Homeland Security Tom Ridge.
None of the living former Republican secretaries of state signed the letter, although Condoleezza Rice's ex-chief of staff, Brian Gunderson, is among the signatories.
House Speaker Paul Ryan is being asked about the Green Bay Packers, not his Republican primary, during a campaign swing.
Ryan is making a final push across his southeast Wisconsin congressional district Monday in advance of a primary where he faces a challenge from Republican Paul Nehlen (KNEEL-in). Nehlen has been praised by Donald Trump, but Trump on Friday endorsed Ryan.
Ryan took questions from employees at A&E Tools in Racine after a tour of the manufacturer on Monday. The first question was about what he thought after watching a recent Packers practice.
No one asked Ryan about Nehlen or Trump and Ryan didn't take questions from reporters.
Nehlen posted a video Monday making a final pitch, saying Ryan has failed to secure the border and enforce immigration laws.
Hillary Clinton is promising more support for small businesses as she tours a brewery in Florida.
At 3 Daughters Brewing, a craft beer brewery in St. Petersburg, Florida, Clinton said she wanted to help small companies grow, pledging to be a "small business president." She criticized Republican nominee Donald Trump's business record, saying he had "stiffed" small companies throughout his career.
Trump assailed Clinton's economic promises in a speech in Detroit Monday, arguing that he would do more for jobs and the economy through tax cuts. Clinton did not directly address his remarks at the brewery.
Clinton's tour came as part of a campaign swing through the battleground state focused on jobs and the economy. She also has two rallies scheduled in Florida Monday.
Donald Trump is planning to roll out a slew of new policy proposals in coming weeks as he continues to try to steady his strugglng campaign.
Trump has largely avoided policy specifics in his campaign, focusing instead on broad goals.
Trump says that he will unveil a proposal to reduce the cost of childcare and increase choices for parents.
He says that he has been working on the plan with his daughter, Ivanka, who is one of his top advisers.
Trump also says that he plans to lay out an education proposal that focuses on school choice as well as one addressing law and order that would propose new funding and support for law enforcement officers.
He was discussing the economy before the Detroit Economic Club.
Donald Trump is wrongly claiming that his Democratic rival Hillary Clinton supports the Trans-Pacific Partnership.
Trump claims during an economic speech he's delivering in Detroit that "a vote for Hillary Clinton is a vote for TPP."
He's citing comments made by Virginia Gov. Terry McAuliffe during the Democratic National Convention that he expects Clinton to change her position on the Asia-Pacific trade deal and support it if she's elected to the White House.
Clinton supported the TPP as secretary of state, but announced her opposition last October, saying it failed to meet her test of providing good jobs, raising wages and protecting national security.
Trump has vowed to re-negotiate trade deals to secure better terms for American workers.
Republican Donald Trump says that no business should pay more than 15 percent of income in taxes.
And he's calling for a temporary moratorium on federal regulations.
In a speech at the Detroit Economic Club, Trump is also proposing allowing parents to fully deduct the average cost of childcare from their taxable income.
The current Child and Dependent Care tax credit is capped at 35 percent of qualifying expenses or up to $3,000 for one cared-for individual or $6,000 for two or more.
A senior campaign aide says the proposal would be aimed at working and middle class families and that it would include an income limit, though the person declined to say how much. The person spoke on condition of anonymity to discuss details ahead of the speech.

Donald Trump is overhauling the income tax proposal he unveiled during the Republican primary and increasing the amount that would be paid by the highest-income earners.
Trump says in an economic speech in Detroit that he wants to simplify the tax code to three brackets: 12 percent, 25 percent and 33 percent of income.
That's a change from September, 2015, when he proposed four brackets that would pay zero, 10 percent, 20 percent and 25 percent.
Trump says the "tax simplification will be a major feature " of his plan and calls it "the biggest tax revolution since the Reagan tax reform"
He says, "We will make America grow again."
Experts said his old plan would have increased the debt by as much as $10 trillion over the next decade.
A string of protests during Donald Trump's economic speech in Detroit appear to be coordinated.
About 10 women have individually stood up and shouted "Mr. Trump," followed by questions that have been drowned out by boos. The protests are occurring in intervals every few minutes and each woman has used the same tactic.
Trump himself noted the protests seemed well planned. Trump is at times pausing while the protesters are dragged out and sometimes continuing his remarks. But he has not directly addressed any of the protesters or demanded they be removed as he has at previous events.
Trump is beginning an economic policy speech in Detroit by going after Democratic rival Hillary Clinton. He says she supports policies that have shipped jobs overseas.
He says, "she is the candidate of the past. Ours is the campaign of the future."
Trump is speaking in Detroit, a city that is a symbol of the country's manufacturing decline.
As Trump began to speak, he was repeatedly interrupted by protesters. Security personnel removed the protesters to loud applause from the audience at the Detroit Economic Club.
Donald Trump is being interrupted by three protesters just minutes into a major economic policy speech in Detroit.
Security has removed two women who stood up and began shouting as Trump spoke. One woman stood on a chair and was quickly pulled down and escorted. Another stood up several minutes later and was also removed.
It was unclear what the women were shouting.
Audience members are largely showing support for the women's removal, applauding as security guards lead them out. One person in the crowd shouted, "We love you, Trump!"
After the third protester, Trump said: This is what happens when you go from 35 people to 2,000."
Donald Trump's campaign has pulled his tax plan from his website ahead of a planned relaunch on Monday.
Trump is in Detroit to unveil a new version of his economic plan. He's calling for cutting business taxes, eliminating regulations and boosting domestic energy production. His plan calls for reducing the number of tax brackets down to three.
As recently as Sunday, Trump's campaign website featured his previous tax plan under a section describing his policy positions. The page had said his priorities were to provide middle-class tax relief, simply the tax code, grow the economy and avoid adding to the national debt.
Trump is revisiting his economic plan as he tries to move past a rough patch in his campaign marked by comments that have drawn criticism from both parties.
Donald Trump apparently has won over at least one member of the Bush family.
George P. Bush, the Texas land commissioner and son of former Florida Gov. Jeb Bush, is seen on a video posted online encouraging Republicans to unite behind the Republican nominee. The Texas Tribune reports the video of Bush's remarks was taken Saturday at meeting for state party activists.
He acknowledges that "from Team Bush it's a bitter pill to swallow. But added: "You get back up and you help the man that won and you make sure that we stop Hillary Clinton."
An early favorite in the Republican presidential race, Jeb Bush said in May that he wouldn't vote for Trump. Former presidents George H.W. Bush and George W. Bush have also withheld their support.
Donald Trump is focusing his economic message on boosting jobs and making the country more competitive on a global stage by cutting business taxes, reducing regulations and increasing domestic energy production.
With a speech Monday to the prestigious Detroit Economic Club, the Republican presidential nominee seeks to reset his campaign and delve into a subject that is seen as one of his strengths.
The speech also is aimed at showing that Trump is a serious candidate in spite of a disastrous stretch that prompted criticism from Republicans and Democrats alike.
While polls have shown that voters have deep concerns about Trump's temperament and fitness for office, recent polling puts him ahead of or on par with his Democratic rival, Hillary Clinton, on who people trust on the economy.
