DHAKA: As opinion polls suggest Donald Trump is gaining support, Hillary Clinton has been holding rallies in states that had been considered safe for the Democrats.
A BBC reported that both teams are now concentrating more on getting their supporters to vote rather than swaying those undecided.
Thirty-seven million early ballots have already been cast.
US authorities say they are assessing the credibility of information on a possible al-Qaeda terror attack.
New York, Texas and Virginia are believed to be the potential targets mentioned in connection with a possible attack before Election Day on Tuesday, but a police spokesman said the information “lacks specificity”.
Officials say they regularly assess all possible threats before major events.
News of a possible attack came as both Clinton and Trump made final pushes for support in battleground states across the US.
They both held rallies in Ohio and Pennsylvania, two states that may prove crucial on Tuesday.
In Cleveland, Ohio, Clinton ended the day’s campaigning at a concert, where she was joined the rapper Jay Z and his wife, the singer Beyonce.
Trump, meanwhile, told a crowd of supporters in New Hampshire that his rival wants a “550 percent increase” on Syrian refugees allowed into the US.
Earlier, at a rally in Pittsburgh, Pennsylvania, Clinton said that her opponent was ‘unfit’ for office because of his temperament and disparaging comments about women and minorities.
The Democrats’ campaign chief, John Podesta, said Trump should ask the governor of New Jersey, Chris Christie, to step down as the head of his transition team after two of his aides were found guilty of orchestrating traffic jams in New Jersey as an act of political retribution against a local Democratic mayor.
Christie has denied any involvement.
Trump is currently ahead in Ohio, according to a state polling average by Real Clear Politics, while Clinton leads by a small margin in Pennsylvania.
National polls have suggested that the Republican candidate has gained substantial ground on his rival in the last week or so.
That momentum also appears to have helped him in several key battleground states.
