U.S. President Donald Trump’s approval rating has ticked slightly lower in recent days as more Americans worried about the direction of the U.S. economy as the new leader threatens a host of countries with tariffs, a Reuters/Ipsos poll found.

The six-day poll, which closed on Tuesday, showed 44% of respondents approved of the job Trump is doing as president, down from 45% in a Reuters/Ipsos poll conducted January 24-26. Trump’s approval rating stood at 47% in a January 20-21 poll conducted in the hours after the Republican’s return to the White House.

The share of Americans who disapprove of his presidency has risen more substantially, to 51% in the latest poll, compared with 41% right after he took office.
