Support for U.S. President Donald Trump has increased among Republicans after his 'racism row' with four minority Democratic congresswomen, an Ipsos poll has found.

The national survey was conducted on Monday and Tuesday after Trump told the lawmakers they should 'go back and help fix the totally broken and crime infested places from which they came.'

It showed his net approval among members of his Republican Party rose by 5 percentage points to 72%, compared with a similar poll that ran last week.

Trump, who is seeking re-election next year, has lost support, however, with Democrats and independents since the Sunday tweetstorm.

Among independents, about three out of 10 said they approved of Trump, down from four out of 10 a week ago.

His net approval - the percentage who approve minus the percentage who disapprove - dropped by 2 points among Democrats in the poll.

Trump's overall approval remained unchanged over the past week. According to the poll, 41% of the U.S. public said they approved of his performance in office, while 55% disapproved.

All four U.S. representatives - Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts and Rashida Tlaib of Michigan - are U.S. citizens. Three were born in the United States.

The public response to Trump's statements appeared to be a little better for him than in 2017, after the president said there were 'very fine people' on both sides of a deadly white nationalist rally in Charlottesville, Virginia.

In that instance, Trump's net approval dropped by about 10 points a week after the Charlottesville rally.

This time, while Democrats and some independents may see clear signs of racial intolerance woven throughout Trump's tweets, Republicans are hearing a different message, said Vincent Hutchings, a political science and African-American studies professor at the University of Michigan.

'To Republicans, Trump is simply saying: 'Hey, if you don't like America, you can leave,' Hutchings said. 'That is not at all controversial. If you already support Trump, then it's very easy to interpret his comments that way.'

By criticizing liberal members of the House, Trump is 'doing exactly what Republicans want him to do,' Hutchings said. 'He's taking on groups that they oppose.'

The Reuters/Ipsos poll was conducted online in English and gathered responses from 1,113 adults, including 478 Democrats and 406 Republicans in the United States.

It has a credibility interval, a measure of precision, of 3 percentage points for the entire group and 5 points for Democrats or Republicans.

The results showed strong Republican backing for Trump as the Democratic-led U.S. House of Representatives passed a symbolic resolution on Tuesday, largely along party lines, to condemn him for 'racist comments' against the four Democratic lawmakers.

The vote was 240 in favor with 187 opposed. Four Republicans and Justin Amash, the Republican lawmaker turned Independent, voted with Democrats to condemn the president.

As soon as the vote was over, Democratic Rep. Al Green brought articles of impeachment to the House floor against the president to try and force a vote on the matter.

Green said Trump 'has demonstrated that he is unfit to be president and has betrayed his trust as president of the United States to the manifest injury of the people of the United States and has committed a high misdemeanor in office.

'Therefore, Donald John Trump, by causing such harm to the society of the United States, is unfit to be president and warrants impeachment, trial and removal from office.'

But the presiding House officer said a determination would be made on his resolution at the appropriate time, which is a way for Democratic leadership to stall on the matter.

Leadership essentially has three options on Green's resolution: table the impeachment articles, which could put them under fire from liberals; refer them to the House Judiciary Committee; or allow the vote to proceed.

Speaker Nancy Pelosi called the president a 'racist' on the House floor

Green also tried to force a vote on impeaching Trump in 2017 but only 58 Democrats supported his move.

The debate over the condemnation of the president's tweets brought chaos to the House floor and froze the chamber for over an hour after a Republican lawmaker objected to Speaker Nancy Pelosi calling the president a 'racist.'

'I stand by my statement. I’m proud of the attention being called to it because what the president said was completely inappropriate,' Pelosi told reporters in the Capitol as the House voted whether or not to strike her remarks from the record.

The Democratically-controlled chamber sided with Pelosi and allowed her comment to stand: 190-232.
