Donald Trump may be riding a high off his recent positively-reviewed first speech to a joint-session of Congress, but he's still the least-popular incoming president in modern American history, according to a daily survey published by Gallup Monday.

The president’s disapproval rating continued its slow decline in the week after Trump's speech Tuesday, down six percent from a Pew research Center poll published Feb. 16. Meanwhile, Trump's approval rating climbed somewhat to 43 percent, up five percent from the same February poll.

Though most polls have varied somewhat in the president’s overall approval and disapproval ratings, other surveys reflected a similar jump in popularity following Trump’s speech to Congress last week. Trump called for unity and strength Tuesday, promising to go forth with his campaign promise of constructing a wall along the U.S.-Mexico border, curbing violence and drug trafficking, as well as urging his counterparts in Congress to end "trivial fights."

"As we speak, we are removing gang members, drug dealers and criminals that threaten our communities and prey on our citizens," Trump said Tuesday. "Bad ones are going out as I speak tonight and as I have promised."

His slight boost in popularity could quickly fade, as new revelations of his top aides' ties to Russia have continued to make international news, including reports his Attorney General Jeff Sessions met with the Russian Ambassador to the U.S. twice while serving as an official member of the Trump campaign.

Trump was reportedly upset the controversy surrounding Russia was still being discussed following his widely-approved speech, venting his frustrations across Twitter and asserting new allegations his predecessor, former President Barack Obama, was wiretapping his phones in Trump Towers during the election – an unfounded claim aggressively denied by Obama, White House and national security officials, as well as several of Trump's aides.

Trump's first 100 days in the Oval Office were still on their way to being the least-approved of any president’s in modern history, trailing behind his predecessor, who enjoyed historically high popularity as an incoming president.
