A Reuters/Ipsos poll of 1,166 respondents conducted Friday through Monday found 33 percent of Americans approve of President Trump’s job performance and 64 percent disapprove. The survey, released Monday, showed a two-point decline from an earlier poll this month and a 31-point approval-disapproval gap. Eighty percent of respondents said the conflict with Iran, now nearly six months old, is likely to continue for an extended period.
