DHAKA: Donald Trump and Hillary Clinton have made renewed attacks on each other’s fitness for office as polls suggest the race for the White House is tightening.
BBC reported that Clinton who has seen her national opinion poll lead shrink in recent days - targeted her Republican rival’s temperament and attitude to women.
Trump claimed she would be followed into the White House by criminal investigations.
He was boosted by a rare campaign appearance by his wife Melania.
In her first speech since July’s Republican convention, the former model spoke about being an immigrant and a mother and said her husband would “make America fair”.
She also vowed, in a speech in the Philadelphia suburbs, to lead a campaign against cyber-bullying if she becomes first lady, and to combat a culture that has “gotten too mean and too rough”.
She made no reference to her husband’s record of name-calling on social media.
Trump has gained ground on Clinton in a number of swing states, such as Florida and North Carolina, according to polls.
Some national tracker polls are now suggesting the two candidates are neck-and-neck.
The Reuters/Ipsos States of the Nation project estimates Clinton’s odds of winning the necessary 270 Electoral College votes on Tuesday at about 90 percent, down from 95 percent last week.
The momentum appears to be with Trump, who has joked about having to stay on message, as the final weekend of campaigning approaches.
He has capitalized on a new FBI investigation into a Clinton aide’s emails.
Later, at a night-time rally in North Carolina, Trump delivered a speech on defense in which he said he could not imagine Clinton as commander-in-chief.
Clinton continued to focus on Trump’s character, telling a rally in North Carolina: “He has spent this entire campaign offering a dog whistle to his most hateful supporters.
“This has never happened to a nominee of a major party.”
She added: “If Donald Trump were to win this election we would have a commander-in-chief who is completely out of his depth and whose ideas are incredibly dangerous.”
President Barack Obama has been working almost as hard as Clinton, as he attempts to rally support among young voters and African Americans.
Analysis of early voting returns suggests black voters may not be turning out in the kinds of numbers they did for Obama in 2012.
Clinton also got a boost from her one-time rival for the Democratic nomination, Bernie Sanders.
He appeared alongside her at a rally in North Carolina on Thursday evening, praising her commitment to increasing the minimum wage and tackling inequality.
Music star Pharrell Williams was also at the event, hailing Clinton’s record on women’s rights.
