FBI Director James Comey lit the fuse Monday on a political time bomb and no one knows — including him — how long it will take to burn or what kind of damage it may cause when it goes off.

Comey confirmed to members of Congress that his investigators are looking into possible collusion between the campaign that elected President Donald Trump and the Russian government. In fact, he said, the FBI has been doing so since last July.
