If a recent poll is to be believed, 4 in 10 registered voters already support impeaching US President Donald Trump, highlighting growing suspicions surrounding his ability to lead less than two weeks after taking office.

In the survey, 40% of voters surveyed this week said they favour removing Trump from office, up from 35% who endorsed impeachment when asked a week earlier, according to polling firm Public Policy Polling (PPP).

Less than half of those polled this week – 48% — said they oppose impeachment, according to the results of the survey, the Washington Times reported.

“Usually a newly elected President is at the peak of their popularity and enjoying their honeymoon period after taking office right now”, PPP President Dean Debnam said in a statement. “But Donald Trump’s making history once again with a sizable share of voters already wanting to impeach him, and a majority of voters wishing they could have Barack Obama back”.

Indeed, 52% of voters surveyed this week told pollsters they would rather have Barack Obama in the White House, compared to 43% who said they prefer the newly inaugurated President over his predecessor.
