Washington | With US President Joe Biden approaching his 100th day in office this week, a slim majority of Americans approve of the job he is doing, but he has been unable to overcome the country’s entrenched partisan divide, according to separate polls released on Sunday (Monday AEST).

The surveys, from Fox News, NBC News and ABC News/The Washington Post, found that Mr Biden is considerably more popular at the 100-day mark than his predecessor, Donald Trump, but his approval is well behind that of most other modern presidents at this point in their first terms.
