An affidavit unsealed by US prosecutors on Monday has underscored the unlawful character of the Trump administration’s request that WikiLeaks founder Julian Assange be extradited to the US in the wake of his illegal expulsion from Ecuador’s London embassy and arrest by the British police last Thursday.

The affidavit was made by Federal Bureau of Investigations (FBI) special agent Megan Brown on December 21, 2017, in support of two charges which had been secretly filed against Assange, under her name.
