Donald Trump's attempt to overturn the result of the 2020 presidential election has left US taxpayers with a bill topping US$500,000 ($695.6m)
According to the Washington Post, at least US$488m has been spent by the federal government and another US$28m by states in dealing with the January 6 siege of the US Capitol and stepping up security in its aftermath.
And an avalanche of unsuccessful court cases brought by the "Stop the Steal" campaign has run up a legal bill exceeding US$2.2m.
An estimated 25,000 troops were deployed in Washington DC after the uprising at the Capitol, which claimed five lives. With plans to maintain the security measures until mid-March, the bill is likely to increase further.
