Washington: US President Donald Trump's approval ratings have hit an all-time high during the coronavirus crisis, with a majority of Americans saying they approve of his handling of the pandemic.

The development - evident across a range of recent polls - has astounded Trump's critics who expected the American public to judge him harshly for his often misleading and erratic response to the outbreak.

The country's two most closely-watched polling aggregators both show Trump recording his best approval ratings since he took office. RealClearPolitics puts him at 46.3 per cent approval and Nate Silver's FiveThirtyEight at 44.6 per cent.

Trump's approval ratings have moved within a narrow range throughout his presidency, but have reached as low as 36 per cent in the past.
