Most people believe President Trump is keeping the promises he made during his campaign, according to a new poll released hours before the president will deliver his first address on Tuesday to a joint session of Congress.

Fifty-six percent of voters in the latest Politico/Morning Consult survey said Trump has already taken steps to fulfill the promises he made to his supporters, whether they agree with his actions or not. A third of voters said he has accomplished more than they expected he would during his first month in office.

The same poll found that 50 percent of voters approve of the job Trump is doing, marking a two-point increase since voters were last surveyed earlier this month. Other national tracking polls have shown Trump's approval rating dipping into the low 40s, and in one case dropping to 38 percent.

According to White House officials, Trump will spend the first half of his speech before Congress recounting the promises he made and has so far kept during his first 40 days in office. The address will focus on "renewing the American spirit" and instilling a sense of optimism in the millions who are expected to watch the president speak.

"Americans have been waiting for help from their leaders for too long and during his speech the president will let them know that help is on the way," said one source.

The survey of 2,000 registered U.S. voters was conducted between Feb. 24-26. Results contain a margin of error plus or minus 2 percentage points.
