Trump 'compromising' claims: How and why did we get here?

Last April, the CIA director was shown intelligence that worried him. It was - allegedly - a tape recording of a conversation about money from the Kremlin going into the US presidential campaign.

It was passed to the US by an intelligence agency of one of the Baltic States. The CIA cannot act domestically against American citizens so a joint counter-intelligence taskforce was created.

The taskforce included six agencies or departments of government. Dealing with the domestic, US, side of the inquiry, were the FBI, the Department of the Treasury, and the Department of Justice. For the foreign and intelligence aspects of the investigation, there were another three agencies: the CIA, the Office of the Director of National Intelligence and the National Security Agency, responsible for electronic spying.

Lawyers from the National Security Division in the Department of Justice then drew up an application. They took it to the secret US court that deals with intelligence, the Fisa court, named after the Foreign Intelligence Surveillance Act. They wanted permission to intercept the electronic records from two Russian banks.

Their first application, in June, was rejected outright by the judge. They returned with a more narrowly drawn order in July and were rejected again. Finally, before a new judge, the order was granted, on 15 October, three weeks before election day.

And from the Guardian:

Why James Clapper's Trump comments may not conflict with reports of secret court order

The News Corp-owned Heat Street news site and later the BBC published reports in November and January respectively that a secret surveillance order had been issued by a special court allowing the justice department to investigate two Russian banks suspected of being part of the Kremlin’s efforts to hurt Hillary Clinton’s campaign and aid Trump’s.

The BBC said the justice department request had originally been based on a tip-off from an intelligence agency in one of the Baltic states, saying that the banks were being used to channel Kremlin money into the US presidential campaign.

Both reports said the Foreign Intelligence Surveillance Act (Fisa) court gave permission in mid-October for monitoring of the activities of the two banks that also covered Trump associates.

Louise reported it on Nov. 7, 2016. The BBC followed on Jan. 27, 2017.
