Donald Trump has gained on Hillary Clinton among US voters this week, cutting her lead nearly in half, according to a Reuters/Ipsos poll.
Clinton, the Democratic former secretary of state, led Trump 44 per cent to 40 per cent, according to the October 14-20 poll, a 4-point lead, with the November 8 election fast approaching.
The latest results compared with 44 per cent for Clinton and 37 per cent for Trump in the October 7-13 poll released last week.
Clinton's lead also shrank in a separate four-way poll that included alternative party candidates: 43 per cent supported her, while 39 per cent supported Trump, 6 per cent supported Libertarian candidate Gary Johnson, and 2 per cent supported Jill Stein of the Green Party.
The latest reading showed that Trump's deficit narrowed to what it was before a video surfaced on October 7 featuring audio of him bragging about groping and kissing women. Several women have since accused him of making unwanted sexual advances in separate incidents from the early 1980s to 2007.
Trump has denied the allegations, calling them "totally and absolutely false".
The Reuters/Ipsos poll was conducted online in English in all 50 states. It included 1640 people who were considered likely voters, given their voting history, registration status and stated intention to vote. It has a credibility interval, a measure of accuracy, of 3 percentage points, meaning results could vary by that much either way.
