The poll, conducted by Connecticut's Quinnipiac University, showed that 40% of respondents - the highest in seven months - are "satisfied" by how Trump has been managing things since taking office.

Fifty-one percent of voters approve of how Trump is handling the economy, and 70% believe that the American economy is "good" or "excellent, the highest rating since Quinnipiac began including that question in 2001.

Fifty-one percent of American voters approve of the way Trump is handling the economy, and seventy-five percent say that their own financial situation is "good" or "excellent."

This is the fifth poll published in the past few months, and it is the first in which a higher percentage of Americans (48% vs 41%) believe that Trump is more responsible for the current economy than former President Barack Obama.

The poll has an error margin of 3.3 percentage points, and was conducted via phone calls to respondents' landlines or cell phones.
