Six law enforcement and intelligence agencies investigating possible covert Russian aid to Donald Trump and his campaign.

The FBI and five other law enforcement and intelligence agencies have collaborated for months in an investigation into Russian attempts to influence the November election, including whether money from the Kremlin covertly aided President-elect Donald Trump, two people familiar with the matter said. 

The agencies involved in the inquiry are the FBI, the CIA, the National Security Agency, the Justice Department, the Treasury Department’s Financial Crimes Enforcement Network and representatives of the director of national intelligence, the sources said. 

Investigators are examining how money may have moved from the Kremlin to covertly help Trump win, the two sources said. One of the allegations involves whether a system for routinely paying thousands of Russian-American pensioners may have been used to pay some email hackers in the United States or to supply money to intermediaries who would then pay the hackers, the two sources said. 

You know widespread investigations like this don't start unless there is good evidence that one is necessary.

This from Mother Jones: 

That's an awful lot of agencies investigating an awful lot of allegations against an awful lot of people. And as the article says, you can't get a warrant unless you can demonstrate at least some kind of plausible probable cause. That means these folks are working off a lot more than just the famous dossier produced by the ex-MI6 spy.

This could be big.

Let's all stay tuned shall we?
