President Donald Trump's approval rating fell to the lowest level of his presidency, with an overwhelming majority of Americans concerned the U.S. war with Iran will last a long time, according to a Reuters/Ipsos poll that concluded on Monday, Reuters reported. 

Just 33% of respondents in the four-day survey said they approved of Trump's performance in the White House, while 64% disapproved. Trump's approval rating, down from 35% in a poll that closed earlier this month and ​lower than at any point in his current term, has now tied the lowest level of his prior term reached in December 2017.
