President Trump's approval rating has fallen in all 50 states since his inauguration in January, according to a new poll.

A Morning Consult survey found that Trump's national job performance numbers have also dropped since January. In September, 43 percent of respondents said they approved of Trump's performance, and 52 percent disapproved. In January, 49 percent of voters approved of Trump's performance, compared to 39 percent who disapproved.

According to the poll, a majority of voters in 25 states said in September they disapproved of Trump's job performance.

Some of those states include those Trump carried during the 2016 election, such as Michigan, Wisconsin, Iowa and Pennsylvania.

Fifty-one percent of voters in Nevada and Arizona also disapproved of Trump's job performance.

In Florida, Georgia and North Carolina, voters were divided on the president's job performance.

Still, a majority of voters in 12 states, including Wyoming, West Virginia, Alabama and Louisiana, said they approve of Trump's performance.

The poll was conducted from Jan. 20 to Sept. 26 among 472,032 registered voters.

Since assuming office, Trump has struggled to carry out some of his key agenda items, including the repeal and replace of ObamaCare and building a wall along the country's southern border.

On Tuesday, Trump tweeted that he would be using the "power of the pen" to give people great health care since Congress didn't act.
