“We do not pay ransom,” Obama declared, after Trump attacked presidential rival Hillary Clinton over the “scandal” of the US paying $400m to Iran after the nuclear deal last year. The Wall Street Journal reported on Wednesday that US officials secretly sent “wooden pallets stacked with euros, Swiss francs and other currencies” to Iran, and suggested the payment may have been linked to the release of a group of Americans. Trump claimed to have seen a video of the delivery – no such video exists – and said Clinton started the relevant talks. She did not.
