There, indeed, was an FBI wiretap involving Russians at Trump Tower.
But it was not placed at the behest of Barack Obama, and the target was not the Trump campaign of 2016. For two years ending in 2013, the FBI had a court-approved warrant to eavesdrop on a sophisticated Russian organized crime money-laundering network that operated out of unit 63A in Trump Tower in New York.
The more interesting case to me is a different Russian mob money laundering case (the Prevezon case), which was being investigated by… wait for it… Preet Bharara.
Well, it was heading in interesting directions until the key witness (whoopsie!) fell off the top of a building in Moscow yesterday. Russian news sources say it was an accident, but witnesses seem to disagree. That’s okay, though, the case marches ahead under the new US Attorney. Bharara’s replacement is likely to be the son of a former lawyer for the defendant Prevezon, so I’m sure it’ll work out fine.
FWIW, Bharara’s refusal to resign was neither pointless grandstanding nor some scheme to get some critical work done before he got fired. In the event of impeachment, firing a US Attorney investigating matters related to the cause of impeachment is considered obstruction of justice, another charge to pile on the rest–and if it got to that point, it would be both serious and difficult to refute.
