US President Donald Trump's accusations of fraudulent presidential elections in November misled millions of Americans, undermined faith in the electoral system, caused deadly riots, and cost taxpayers massive costs - $ 519 million, The Washington Post reported.

Spending is on the rise day by day as all government agencies have to disburse public funds in response to actions taken by Trump and his supporters, according to records of local, state, and federal spending reviewed by the Washington Post, as well as interviews with government officials.

The costs include legal costs incurred by dozens of fruitless lawsuits, increased security in response to threats against election officials, and costly repairs needed in the wake of the January 6 riots at the US Capitol. The attack led to the costly deployment of thousands of National Guard troops in Washington amid fears of further violence from extremists.

While over $ 480 million of the total is spent on military deployment until mid-March, the financial implications of the president's refusal to step down in the election are likely much higher than has been documented so far, and the real spendings may be never be known.
